Imagine having a teleporting machine in your house. I feel like that’d be pretty dope. I mean like aside from it being possibly one of those things I’d get broke for, I’d definitely try and gather all the cents I have and purchase my own. I’m just blabbing here but LEGIT THINK ABOUT IT. First off, that kind of technology is so cool. bruh. LIKE just calling your friend and be like “Dude yeah I’m just grabbing my bag and I’ll teleport there. Give me like 5 minutes.” WOAH. Wait, would that mean we wouldn’t need like cars and airplanes anymore since the mode of transportation would just be TELEPORTING?!?!?! That’s if the government would install a public device out there for people to use. Which, if teleporting device does successfully get made and operated, I hope they do. But, what’s the current situation on teleportation? Wellllll, taking a few steps back and getting a small glimpse of this sweet sweet thing called quantum physics, there are a few technical difficulties that we seem to discover. This type of transportation requires absolute (ABSOLUTE) precision. From location A to location B, what would be happening is that you’d be scanned at location A and then teleported to location B. Kind of like a fax machine ish, but like on a super extra complicated and subatomic level. Also, not to mention that you will have to technically die first as you’re basically having the (more than) trillion atoms that make up your body be copy-and-pasted into the destination that you plan to be teleported. It would be you but like not really. TAKE NOTE that this reconstruction would have to be exactly precise, else another problem would occur. It’s crazy and there’s just so much to consider when it comes to teleportation and all the nitty-gritty details along with it. There’s more development being discovered with teleportation and quantum entanglement. Although human teleportation currently only exists in the movies, we’re moving forward as teleportation in the subatomic world of quantum mechanics evolve. After doing a little bit more research about this and realizing how the teleportation device would hypothetically work, I’m starting to have second thoughts hahaha. Riding a car and airplane isn’t too bad you know, plus it’s an adventure. So, I might pass on the whole teleportation-copy-paste-atoms thingy for now. So, anywho, that’s the brain pop for today. What do you think about it? If a machine did exist now, would you use it?
Quote of AWESOMENESS: “Life in orbit is spectacular.” – Tim Peake
Morning burst like a bubble as the alarm shouted: “WAKE UP, IT’S 6 AM!“. The sun was showing off as the clouds slowly dispersed until it was nothing but fine grains of salt scattered across the sky. An announcement popped on the news telegram showing the weather and a little notification about all the events and stores that were broadcasting they’re open hours. You decide to go for a little hover as you look up into the thoughtfully designed elevators shooting to the stars. It was a piece of artwork. Luckily, you had put in your schedule to go for a zoom into space today with a couple of friends. You and your friends meet up at one of the elevator points and get in with your special suits (which, by the way, look absolutely amazing) and designed gear. The countdown starts, “Please make sure you’re properly suited up and secured to the wall…. 5…. 4… 3.. 2..”
Before you could say “snickerdoodle”, the elevator starts its ascend into the sky and the ground below you starts to shrink. Your favorite song plays over the speaker as you and your friends start discussing which restaurant on which planet you wanted to try this time……
Okay, maybe the planet-hopping might take a little more brainstorming and planning and researching, but wouldn’t this be such an adventure.
Today we shall be discussing (yes, I know, that was a very formal-serious-big word I just used) the 𝓢𝓹𝓪𝓬𝓮 𝓮𝓵𝓮𝓿𝓪𝓽𝓸𝓻. Okay, so, let us proceed…..
Ideas of the space elevator have already been put out there for quite some time. “What is it?”, you may be asking yourself. Well, basically, it’s an elevator which starts here (on our beautiful planet) and goes on and on and on until space. I know, that would be pretty long. I mean, I already have trouble just thinking about using an elevator with a hundred floors. All fears aside, I would have to admit, an elevator TO SPACE is pretty awesome.
Transportation of goods would be relatively cheaper because aerospace companies wouldn’t have to keep remanufacturing space rockets and other things. We would be moving forward towards ideas on planet-hopping and studying more about the space world and cheering on, as Buzz Lightyear so famously quoted, ” to infinity and beyond!”.
However, there are some elements that would have to be considered and have safety protocols in return. Some are the following:
Conflicts with countries and people who would use this for something other than good
The strength of the material used for building
Passing meteors or space junk that might
To wrap everything up, researchers and scientists are still ongoing with how we are to design this access to space. Ideas keep on coming. It might seem like such a huge project and idea, but researchers are still definitely working to have this in our future.
Quote of TRUTH: “Real stupidity beats artificial intelligence every time” – Terry Pratchett
Over the past years, technology has seemed to advance faster than we could have ever imagined, especially comparing to the Paleolithic times (where all our ancestors had invented were cave paintings and fire pits, which is, by the way, still very awesome to invent). We’ve gone from having our first light bulb flicker into existence then next self-driving cars, like Tesla. Mind-blown, I know, feelings are mutual. But, now, we’re going to talk about something that isn’t common in most places (for now, or so we think), Artificial Intelligence.
1. They’re starting to camouflage with everyone else around them
What I mean by this is that they are starting to look super realistic! We have almost mastered the art of forming technology into such human-looking-like figures. To tell you the truth it is a little bit creepy. One example of this would be Yangyang, a robot which has been created. The features that were given to her have made her an almost replica of Sarah Palin!
Sarah Palin isn’t the only one out there. There’s also Sophia and Nadine. Sophia is pretty well-known as she has been on a couple of interviews. She has even met Will Smith, and she’s actually the first robot to receive a citizenship. Nadine, on the hand, is an AI who works as a university receptionist. She was described as the “world’s most human-like robot”. Aside from looking human, these robots are able to interact as such, too. Nadine has the capability to smile, make eye contact, greet visitors, and even recognize past guests. What happens when you can’t tell artificial intelligence from an actual living and breathing human being? Imagine, just imagine, someone decides to change the entire Madame Tussaud, a wax museum (by the way, people already get confused by whether the wax figures are real or not), into AIs. Just thinking about it gives me the chills.
2. They are taking over our jobs
This problem is something that we’ve got to keep in mind. We’ve created these machines to do all these tasks and finish all these jobs for us. Yet, we somehow seem to be distracted from the fact that this would be very unfortunate for so many families and people out there.
It is estimated that 73 million U.S. jobs would be taken over by robots and automated by 2030. Yes, I actually mean millions. So for every job operated by automation, that’s another job lost for someone or their family. But here’s the wildest thing, the estimate for 73 million jobs lost is just in the U.S. alone. Looking at the bigger picture, a new report claims that, worldwide, an astonishing amount of 800 million jobs would be lost due to automation.
3. ROBOT DOGS!
You read that right. Robot. Dogs. How cool does that sound? Very much, I agree. Having a robot dog eliminates most of the migraines that you would normally get from a normal dog as it wouldn’t have to do his “business”, everywhere, if you know what I mean. The two main things that you wouldn’t have to worry about anymore would be the robot dog’s health and its hygiene.
Sony has actually announced that they would be releasing their robot dog. With a price of $2,899, they have made major improvements such as adding touch sensors for when you pet it, facial recognition for it to know its owners, a camera mapping which it uses to memorize your house’s layout, and it even has voice commands!
4. They are able to teach themselves
Yup, self-taught. The advancement of the technology that has been put in their system has actually allowed them to teach themselves. They no longer need us humans to put more information for them, they can learn what they want to learn. Remember the AI robot I told you about earlier, Sophia? Well, according to the supposed first photographer who stepped inside the Hong King-based Hanson Robotics, Sophia might have self-taught herself what a camera was.
Another example of this would be the AI system that Google has made which taught itself to play Atari 2600 games. A study funded by the Defense Advanced Research Projects Agency (DARPA), showed that their program for their robot was capable of watching videos on how kitchen utensils work and able to properly copy what it saw without any humans to help them out. They even said that by 2029, because of AI increase of knowledge, they would have the same intelligence as us humans.
5. They Can Heal Themselves
The algorithm based on trial and error is what the robot uses to check its system and repair itself. The researcher’s idea is that the robot would act something like an animal and adapt to being broken as they “learn and iterate based on self-reflection”. They have been able to successfully adapt a method similar to this to AI.
Another way that robots were designed to heal themselves was by what material they were made out of. What roboticists did was create soft robots. Soft robots work by heating itself for about 40 minutes at a temperature of 80°C, then after a day when the temperature is at 25°C, the robot would restore after its damages.
6. They’re Being Weaponized
An amount reaching $2 billion dollars is said to be spent alone for AI systems in weaponry. One of the main reasons why the Pentagon and the U.S. military wants to invest this much for their weapons is to stay ahead of other countries around and be more advanced. Even though this would be helpful for an increase in security, there are still dangers that come along with it. The machines that are given the power to control their own actions may put the lives of innocent people at risk, as well.
7. Romantic Relations and AI?
Once our fellow AIs roam the earth and we can’t seem to tell if they’re human or not, there’s a high chance that most people (as in human beings) would have some type of relationship with an AI. Whether it’s romantic or not, the more we put in research and push for these robots to be made, it’s going to be inevitable to not have some contact with one AI or two. There are actually a couple of movies out there that show a glimpse of what people predict the futuristic love life of most to be, such as, Her or Ex-Machina.
According to the report of Dr. Ian Pearson, he says that “by 2050, human-on-robot sex will be more common than human-on-human sex”. Eventually, this idea would be so casual yet looking at it now just seems a bit weird. It looks as if we’re all planning to slowly steer away from humanity and merge as one with technology.
8. They’re Being Taught To Deceive
Claiming for military purposes, a research conducted at the Georgia Institute of Technology by Professor Ronal Arkin and his team have successfully implemented this deceptive behavior into a robot. Professor Arkin and his team first tested out this deceiving behavior with squirrels and birds and when they got the results they also were able to do it with robots.
This is definitely something remarkable yet scary. Even though we are programming this for when they are out at war or during some military business, they can also use these skills if they go rogue. And, how dangerous might that be? Very dangerous, very much indeed.
9. They’re Getting Good at Gaming
These artificial intelligence machines are becoming better and beating us at our own games. Literally. These are the very games that we’ve created. The games that only a small percentage of us have actually mastered after the years of practice. It’s all fun and games until it’s not. Right?
There is an artificial intelligence division within Google that is known as DeepMind. The advancement of AI has shown impressive results. They’ve been able to successfully beat our best players at chess, Go, and even Jeopardy using the skill sets that they now acquire.
One of the more famous cases would be google’s AlphaGo computer program designed to play the game Go. This game is something you’d really have to put your brain power to use as proper strategic planning is needed in order to win. And, here’s the craziest part, after just a couple of hours of training this program was able to defeat the world’s best player.
10. They May Possibly Take Over the World
Taking into account all the great progress we’ve done for both the advancement and improvement of Artificial Intelligence is truly remarkable. However, there have been expressed concerns by some of the best minds out there that going through with AI research and development may lead to our ultimate doom.
Stephen Hawking has said that AI is pretty much spelling the end of our human race. Bill Gates is very worried and knows that AI going to pose as a threat to humans. Elon Musk(LINK 20) has thrown concern and warning after warning that continuing on this path to develop AI is dangerous and even compares it to “summoning the devil”.
Artificial Intelligence has already learned to lie, self-study, create, destroy, fight, self-heal, and even think for themselves. We can’t tell the future. We can’t say for sure right now whether this would be the best thing or the worst thing to happen to us. But, what we do know is that our decisions daily to proceed with AI developments is going to affect what happens to us later on. And one day we may have an AI apocalypse but also we might not.
This is our future we’re talking about. Are we willing to risk it all? Hmmm….
Quote of TRUTH: “Security is always excessive until it’s not” – Robbie Sinclair
There was this really cool conference kind of meeting that happened on September 19, 2018, at the University of La Verne. Its main purpose was to teach small business on how to develop themselves. There were plenty of things that they taught like about trade, foreign investment, government contracts, and more. BUT, in this blog, we will be talking about cyber threats.
Ikr sounds super mind-boggling but its OKAY because I shall explain more.
Also before we continue I just need to point out that the speaker for this part of the conference was an FBI Special Agent. super. duper. cool. I know.
OKAY, let’s actually start this.
So, what is the meaning of cyber you may ask? It is of, relating to, or involving computers or computer networks ( as the internet ).
We use devices all the time nowadays don’t we? And, the problem is that every individual with a smartphone are targets for potential hackers.
We can break down Cyber threats into these five categories: (this will be from least problematic to more problematic, but they are all still a problem)
So we have good news and we have bad news…..
I’ll tell you both, starting with the good news:
Down for 2018, so far:
Global ransomware attacks
However for the bad news:
Up in 2018:
Corporate data breaches
Critical infrastructure failures
Internet of Things Attacks
Business Email Compromise
Okay, so the cons may be, slightly, a bit outweighing the pros but I have gathered information on what can be done to level the playing field. If that makes sense.
Some of the big hacks would include the 2014 Sony Hack. Imagine this being a billion dollar company and all their files were hacked and stolen. This was very stressful for them. Another one would be how hackers got into a Hollywood Hospital and took control of their systems and blackmailed them to give them $17,000 in bitcoin if they wanted them back. In case you were wondering, the bad guys got away with their money as they were paid what they wanted.
These are examples of Ransomware.
RANSOMWARE? I’ll explain. It is 1) a very big threat and 2) kinda really scary when it happens. In other words, this is a type of malware that would ask you for a ransom if you want your files or computer access back. And, if you don’t give the money then there’s a big chance you won’t be getting your stuff back. How is this a very big deal? Well, okay, imagine this. You are driving in your all new and improved-futuristic-technology-filled tesla car when suddenly the iPad on the computer starts to malfunction. A message then pops up and it reads “If you want to have access to your brakes, pay up $120,000 now”. You freak out and hit the brakes but nothing happens and your speed starts to accelerate. Fortunately, you just had the biggest paycheck ever and you were able to make a wire transfer of $120,000 to the encrypted bank account number they’ve given. And, your car then goes back to normal and you safely drive back home. But what happens when you don’t have the money or you’re just stuck in your car because of someone who hacked your car. Very scary and dangerous thing indeed.
Another kind of hacking that seems to regularly occur would be the business email compromise (a.k.a B.E.C). This happens when a hacker gets into your email and tricks you into paying your house, bills, or other things and instead the money gets sent to them. This happens all the time because the email received looks very legit. Especially in real estate. So much money gets lost.
Hackers hijack emails in 4 easy steps:
They use an email extractor which you can easily access
Hacker sends a fishing email out to thousands of emails
They research everything about like how you and the person you are negotiating with speak with each other and the deals made
The hacker uses the information they found to send the homebuyer a message telling them to reroute their bank account.
Imagine this is how simple it is for them. And yet in the process, there are families out there that lose their life savings because of these evil deeds. YOU need to make sure to ALWAYS check for authenticity. Example of this would be to call up the person you’re making a deal with and double check to see if they’re the ones who sent you an email.
Did you know that the average B.E.C loss is $130,000?
You can actually even buy legit emails for just $11.00 just by looking it up on google. All the hacker needs to do is to buy a piece of software or malware which is just up to $25 dollars to do all this damage. There are tons of people who get victimized as they are unaware of fishing emails sent to them. 91% of cyber attacks and resulting data breaches happen with email.
HACKER: Mistah X
Victims- mostly women
Uses the person’s computer camera to record just whatever they do and uses it to blackmail them
He uses a software
He was put in jail but was recently released, that means he is out there
HACKER: Christopher Chaney
He had no programming experience whatsoever
Christopher Chaney would use a notepad to list down all the details of a celebrity and open up their emails. Then, he would go to the forget password part and answer the “secret” questions that they give. Since celebrities nearly give all their information to the world it wasn’t that difficult for him to hack into their emails with what he got.
Used spoofed domains “typo-squatting”
Stole about $1 M
He only had minimal hacking skills
See how these people barely required to have extensive hacking skills yet they’ve done all these? It’s so easy to get hacked which is why cybersecurity is very important. Small business is the target of 58% of all malware attacks which is shown in the Verizon insights report statistics of 2018.
Now, what can we do about this?:
Have a multi-factor authentication (which is requiring two things to access something, like your email):
This reduces the chances of having personal information being stolen
It is free for most devices
Beware of SIM swap hack
Backup data on Hard Drive:
This way you would have your files in a potential ransomware attack
Have a good password
Remember there is nothing foolproof and it’s so much better to take extra precautions.
Good practices to prevent this from happening to you:
Back your data regularly
Use strong passwords and change often
Educate others on this
Have a network security plan & actually implement it
Establish a cybersecurity policy
Conduct tabletop exercise for an incident
Update your software
Have a robust process for financial transfers
Even if though these were the tips given to businesses to protect themselves from cyber threats, you should use these too to protect yourself! Spread the word because this is something definitely everyone should be aware of!
Let’s paint an image, imagine a world where everything is super advanced. Where you could actually see flying cars instead of youtube videos of it saying that they exist. And, a world where the sky is truly the limit and people take advantage of it, in a good way. A world where you put on your calendar to meet up with your cousin who recently moved to mars for a few days then return back to earth. Another way to see this would be a world that also has the same technology as seen in Wakanda (to all those whose seen Black Panther “WAKANDA FOREVER!!!”).
Okay, okay back to the topic. Wait, what was it again?
Oh, yeah, having a really really really advanced world which is in no comparison to our world (for now).
Let’s explore more about this with Michio Kaku in his chapter on advanced civilizations. Who is Michio Kaku exactly? First, in my opinion, he is an awesome scientist. He is also an American theoretical physicist, futurist, and popularizer of science. Okay, now that we’ve covered that back to advanced civilizations. It was actually in 1964 when Russian astronomer Nikolai Kardashev introduced the classification of advanced civilization. Initially, Kardashev came up with 3 types of civilizations which are the following:
Type I civilization:
a.k.a the planetary civilization
this civilization would be able to employ all the energy that reaches the planet and all the energy it can produce
This energy is solar, thermal, hydro, wind, and more
Michio Kaku predicts we would have control over things such as earthquakes, the weather, and volcanoes
With research, it was found that this type of civilization would harness the power of 7 x 107
To get to this state, we would have to boost our current energy production to 100,000 times
We are estimated to reach this stage in about 100-200 years
Type II civilization:
Would also probably be classified as an interplanetary civilization, too
We would be able to use the total energy of our sun (a star)
Have the ability to move planets and stars
To accomplish harnessing the energy of a star, we would be using a megastructure called the Dyson Sphere
We are estimated to reach this stage in about 1000-2000 years
Type III civilization:
at this point, everything would be different from today
We’d have space travelers zooming everywhere
And, the norm would possibly be cyborgs
We would also have the power to use the energy of an entire galaxy
This, as Michio Kaku is estimated to happen in about “one hundred thousand years and possibly not for a million years”
Type o to Type I
In case you were wondering, we are a Type o at the moment and for quite some time, too. The first thing that we would have to do is change from Type o to Type I. Now, we have some obstacles that are preventing and slowing down the process of actually advancing forward and helping our world socially and technologically to reach the next stage. As Michio Kaku writes, “the biggest threat facing a Type I civilization may be a self-inflicted one” and some of the challenges include “global warming, bioterrorism, and nuclear proliferation”.
Problems preventing the transition from Type o to Type I
Expanding on the problems, global warming, which has been a threat to humanity has countless evidence which Kaku notes, the following:
EVERY major glacier on the Earth is receding
The Northern polar ice has thinned by an average of 50 PERCENT over the past fifty years
Large parts of Greenland, which are covered by the world’s second-largest ice sheet, are tawing out
A section of Antartica the size of Delaware, the Larsen Ice Shelf C, broke off in 2017, and the stability of the ice sheets and ice shelves is now in question
The last few years have been the hottest ever recorded in human history
The Earth’s average temperature has increased by the 1.3 degrees Celsius in the past century
On average, summer is about one week longer than it was in the past
We are seeing more and more “one-hundred-year events,” such as forest fires, floods, droughts, and hurricanes
Another great danger which the world and humans face which have been there for quite some time is diseases, plagues, and epidemics. The influenza epidemic killed an estimate of 50 million people whereas the war itself had it’s estimated down to 20 million less than that of influenza. The problem with this? There is such a thing as a weaponized biogerms. Yes, I know, terrible, if there is such a ferocious disease which gets created and released it has the potential to eliminate 98% of the human population! These are some of the things that have made it difficult for our advancement. Breaking from this would be a difficult job and a challenge when we emerge to a new civilization. But, if we work together, stop the competition, the inequality and put our awesome minds together, maybe we could transition to a better and advanced civilization compared to where we are now.
Future civilizations may change and evolve. But, with the decisions that are made today, in this century will help in determining whether that change would be better or for worse. If we take the right steps and choices, it may be possible to be living in a world where we have laser porting (which is a future way of traveling[g to the stars in light speed), space elevators, programmable matter, robotic construction, fusion power, asteroid mining, and a better-civilized world….
….and maybe (MAYBE) we might be living in a really cool world like in WAKANDA. Am I right?!?!
Hope you’re having an awesome day, afternoon, or night! Till the next blog, bye!!

Level of hardness: intermediate (You can do this!)
Heyyy!!!! Here’s another Arduino project for you!
For this project, you will need the following:
1x Arduino UNO Board
1x USB Cable Type A/B
1x RGB LED
3x 220-Ohm Resistor
3x 10k-Ohm Resistor
13x Jumper Wires
The first step is two connect your breadboard to your Arduino and it should look something like the photo above. Then, add your RGB LED to your breadboard.
Next, you need to grab another wire and connect the other positive lane of the breadboard to the negative lane on the other side of the breadboard.
In this step, we will be placing the three 220-Ohm Resistors to three of the legs of the RGB LED. You will only be placing the resistors on the R, G and B of the RGB LED, this will leave you with one leg unconnected.
For this step, you will be needing four wires. Remember I told you that you were left with one leg of the RGB LED which isn’t connected? Well, it’s time to connect it now! Place one end of the wire to the remaining leg of the RGB LED then place the other end to the negative lane of the board. In the photo, the wire which I used for this connection is white.
With the other three wires, connect it to each of the 220-ohm resistors. Then, connect the other end of the wires to the Arduino 9, 19, and 11.
Let’s place the photo-resistors on the breadboard so that they cross the center divide from one side to the other.
Now, connect the 10k-Ohm resistors to one side of the photo-resistors and the other side to the negative lane of the breadboard.
Taking three other wires, connect it between the photo-resistor and the 10k-Ohm resistor then connect the other end to the Analog In pins 0, 1, and 2 on the Arduino.
Going on the other side of the photo-resistor, connect each leg to the positive lane of the Arduino with three wires.
Your result should look something like this!
This is the final step! Connect your Arduino to your computer, fire up your Arduino and copy paste in the following code:
const int greenLEDPin = 9; const int redLEDPin = 11; const int blueLEDPin = 10;
const int redSensorPin = A0; const int greenSensorPin = A1; const int blueSensorPin = A2;
int redValue = 0; int greenValue = 0; int blueValue = 0;
int redSensorValue = 0; int greenSensorValue = 0; int blueSensorValue = 0;

Here’s a short review 🙂
The Google Home Mini can be really helpful. Have a question? Ask your google home mini! It’s that simple. Your questions can be as simple as “what’s the weather, today” or as complicated as asking how to create a ratatouille dish. Did you know that even music could be played by this? Exactly, I was mind-blown too.
All you need are two words and you would have access to so much more. Want to know these magic words? Yeah, me too!
It’s a simple “Okay, Google.”
If you are at good range distance (enough for the device to pick up what you are saying, otherwise you would have to be screaming “OKAY GOOGLE!!!”) then four little dots at the top would light up. This indicates that the Google Home Mini is listening and waiting for you to speak.
But, the thing is, when you want to listen to music on youtube from your Google Home Mini, you will have to add your Youtube Red account to the mobile app connected to your Google Home device. This is one of the irritating things about Google Home Mini.
A FEW OF THE MANY THINGS WE CAN SAY TO GOOGLE HOME MINI:
Set an alarm
Set a date
The weather update (although you can look outside your window, too)
Translate from different languages
And, way more!
Google Home even tells jokes! And, if set up properly, you can connect your device to your lights and switch it off or on with a few words! Pretty cool, I know.
This project is just extremely awesome and awe-spiring that I can’t wait for you guys to try it out!
We. Are. Going. To. Make. An. Arduino. Robot. Arm!!!!!! I know, I know super cool. Now, without further ado, let’s jump right into this project.
The following are what you will need to gather:
1x Arduino UNO Board
1x USB Cable Type A/B
2x 10k-Ohm Resistor
5x LED (A.K.A light-emitting diode, A.K.A miniature looking light bulb-ish)
5x 220 Ohm Resistor
20x Jumper Wires
First, let’s start by putting the potentiometers, the buttons, and the LED’s on our breadboard.
We will be placing 3 potentiometers, 2 buttons, and 5 LED’s. For your reference, the photo above can help. Yes, I did say 5 LED’s but I forgot to place the fifth LED in this photo, but you should put 5.
Here are some important basics to understand about an LED:
Cathode (-, shorter side)
Anode (+, longer side)
RESISTORS. Resistors. resistors.
Place five of your 220 Ohm Resistors on each of the Anodes (+) sides of each of your LED’s and the other end of the resistor to the negative side lane on your breadboard which we will later connect to the GND on your Arduino board. I’ve placed another photo above showing where I’ve placed my 220 Ohm Resistors.
Now, take both of your 10k-Ohm Resistors. You will have to place one side of your resistor to only one of the button’s leg. Do this for both buttons. Here is another picture but of the buttons and resistor placing.
We have finished placing all the resistors we will be needing in this project. You guys are doing an awesome job, btw!
This step will be really quick.
All we need to is get two jumper wires, first. Then, connect the Negative lane on your breadboard to your GND on your Arduino, and, the positive lane of on your breadboard to the 5V on your Arduino (you can find this right beside the GND, usually).
Done with this step. Great job!
For this step, you will be needing 5 of your jumper wires.
We will be connecting each of the LED’s on the breadboard onto the Arduino UNO board with your jumper wires.
Here is the first LED I connected. We will be connected the other leg (cathode, shorter side) of the LEDs to these numbers on the Arduino in order:
I will also be numbering the LEDs on the next photo so that it will be easier to know which we will be connecting to which.
We will connect:
LED 1 to 2 on the Arduino board
LED 2 to 3 on the Arduino board
LED 3 to 4 on the Arduino board
LED 4 to 7 on the Arduino board
LED 5 to 8 on the Arduino board
I know that wiring could be a tedious job but it’s okay because I know you can do it.
Wiring is very important because it connects. It works as that bridge that can help cars go back and forth and connect with other cities. If you have a bulb and a power source you can’t just put it beside each other or clink it together to light the bulb up (even that would be super cool if that’s how easy it was), you need to connect it through wires. So, let’s continue? Yes.
In this step, we will be wiring the buttons and the potentiometers.
Here in this photo I got two jumper wires and connected one end to the remaining unconnected leg of the buttons and connected the other side of the jumper wire to the positive (+) lane on the breadboard
That was easy, wasn’t it?
We are nearly done!
Let’s start wiring the potentiometers now.
For the potentiometer, it’s going to be slightly harder.
In this photo, I’ve connected 3 jumper wires to the right side of the potentiometer then connected the other end of the wire to the Negative lane of the breadboard (A.K.A GND).
And, then, I got 3 more wires and connected it to the left side of my potentiometer then connected the other end to the Positive Lane on the breadboard.
I’ve added the numbers on top of each potentiometer so that it’s easier to understand how to connect it to the Arduino.
As you may see on the picture to your left, I’ve added 3 white jumper wires to each of the middles of the potentiometers because we will connect this to the Arduino Board. Connect potentiometer 1 to the A0 on the Arduino UNO Board | Connect potentiometer 2 to the A1 on the Arduino UNO Board | Connect Potentiometer 3 to the A3 on the Arduino UNO Board.
In this step, grab two more jumper wires and connect both ends of the lanes on each side of the breadboard to each other. I used the black and red wire here.
You will need to connect the Negative lanes on each side to each other and the Positive lane on each side to each other.
Tada! Next step.
We are nearing the last of our steps. KEEP GOING!
We will add the servo motors to our breadboard and I put mine side by side to each other.
I connected three jumper wires each for three of my servos, meaning 9 jumper wires in total.
About servo motors in Arduino:
They usually have 3 plug pins (this is where I connected my jumper wires to)
Take a look at your servo motor. You will probably notice there are three colored wires. Each color represents 3 different things. The colors could actually be different sometimes but, as you see here, my colors are brown, red, and yellow.
The brown is the Ground/Negative (-)
The red is Positive (+) [This wire is usually located at the center of all the three wires]
The yellow is the Signal
Your wires on your servo motors might be different and you might be thinking “WHAT!?!?” but it’s okay (that’s what I thought too) here is how you can compare it to mine to find the similarities:
The Ground/Negative is usually | Black or Brown (in my case, it’s brown)
The Positive is always Red
The Signal can be either | Orange, Yellow, or White (in my case, it’s Yellow)
Awesome, let’s proceed.
These are what you need to connect with your Servos:
Connect each of the GND/Negative (Black or brown wire) on each of your servo motors to the positive lane on your breadboard (I used a white jumper wire, check the photo above for reference)
Connect each of the Positive (Red wire) on each of your servo motors to the negative lane on your breadboard (I used an orange jumper wire)
Lastly, connect each of the signals (Orange, Yellow, or white wire) of your servo motors to: 5, 6, and, 9 on your Arduino
This is our last time! Congratulations!!!
Connect your Arduino to your computer, fire up the Arduino app on your computer, copy paste the code below and press Upload.
Now, the challenge whether you choose to accept it or not is to build your own robot arm out of cardboard or you can check this —-> here which was made by Ryan Chan. Shoutout to him, btw. I hope you enjoyed this! I certainly had an awesome time and I hope you did, too!
You can teach others and share your awesome knowledge on building an arduino robot arm, I give some bragging rights.
You grab out your phone as you took a seat next to a coffee shop which had a big sign saying “FAST AND FREE INTERNET HERE”. Once you’ve connected to their internet, the page you searched loads slow, really slow. When you look around to see if anyone else is using the internet there’s about 0-2. You try going closer to the router, but nothing changes….
Have you been in this type of situation?
With Li-Fi, the way that we do the internet might change. But for the better or for worse?
What is Li-Fi??
Li-Fi stands for Light Fidelity which is a Visible Light Communications (VLC) system running wireless communications traveling at very high speeds. Instead of a router (which Wi-Fi uses), Li-Fi uses light bulbs that help in enabling data transfer and (AND) boosting the speed up to 224 gigabits per second! That’s a lot.
How did it start?
In 2011, Professor Harald Haas from the University of Edinburgh was at a TED talk where he envisioned these light bulbs which could be used as wireless routers. I’d say that’s a pretty cool thing to think about.
You could check out the video of TED here: https://www.ted.com/talks/harald_haas_wireless_data_from_every_light_bulb
How it works
Soooo, how does it work?
Similar to Wi-fi, Li-Fi both transmit data electromagnetically. But, instead of using radio waves (which Wi-Fi uses), Li-Fi runs on visible light!
Just as we said, Li-Fi is a Visible Light Communications (VLC) system which means that it uses a photodetector to receive the light signals. The light signals are then processing element to convert the data into stream-able content.
According to Mercer, “A LED light bulb is a semiconductor light source meaning that the constant current of electricity supplied to a LED lightbulb can be dipped and dimmed, up and down at extremely high speeds, without being visible to the human eye.
For example, data is fed into a LED light bulb (with signal processing technology), it then sends data (embedded in its beam) at rapid speeds to the photo-detector (photodiode).
The tiny changes in the rapid dimming of LED bulbs are then converted by the ‘receiver’ into an electrical signal.
The signal is then converted back into a binary data stream that we would recognize as web, video and audio applications that run on the Internet enables devices.”
Look at the photo above wouldn’t it be so much easier if we received our internet
100 times faster
Li-Fi was tested out in late 2015 by scientists in Tallinn, Estonia. They placed them in offices and industrial environments and they received impressive news. They were able to receive data transmission at 1 GB per second. This is 100 times faster than the current average internets speeds that we have today!
Unlike the internet today which seems to seep out through our walls and going to the neighbors or other public places, Li-Fi provides extra security. Without the light from your Li-Fi, there won’t be any data. So, just by closing your window blinds or you doors you’ll stop anyone from trying to Wi-Fi Spy on you.
And while Li-Fi is safe in security wise, it’s also just safer for us. Since Li-Fi doesn’t do their operation through radio waves and they use light, it doesn’t produce electromagnetic radiation and it doesn’t interfere with existing electronic systems.
Neil Harbisson, born on July 27, 1982, in London, United Kingdom, is a contemporary artist and cyborg activist. Neil actually has this antenna implanted in his skull which makes him “officially” known as a cyborg.
Why did he implant this antenna?
Neil Harbisson was born with complete color blindness. When he was studying in a music composition in England, he somehow got interested in cybernetics which he read could help him to extend senses (Sisley). He started a project with Adam Montandon to make something that would help him to sense color. The first idea was to create this third eye which then led to a better idea into making an antenna which is also similar to how other animals and insects (like bees). From then on (eight years already), he has been hearing color. Now he came from greyscale to a whole new world of colors. He says that “Each color has its own vibration” and that each vibration is felt inside the bone then through your inners which allows you to hear colors.
What does he use it for?
Well, aside from hearing colors, he gets to use it for when he drafts art, symphonies and even his own ‘Cyborg’ foundation. Did you know that he is the first cyborg artist? He is currently working on the first cyborg-focused fashion line with a space concert.
What else can his antenna do?
Aside from hearing colors, his antenna can also perceive invisible colors like infrared and ultraviolet. What’s really cool is that from his antenna he can receive images, videos, music, phone calls or colors from space directly into his own head!
