Thankyou for such a nice explaination. It didn't even seem to me that I am virtually seeing the components but it seemed like everything was just infront of me. All thanks to your efforts of explaining all this in such way. 👍
i dont have much experience in coding, i just know some basics python stuff and web development. this video helps me alot to learn arduino. thanks alot! great teacher 😊
This is the best beginner series I have seen so far. Thanks for breaking this down. It's still very confusing to me (the code), but I am just going to follow from the very beginning. That Tinkercad program is outstanding for this! I struggle to see the holes and numbers on the boards breadboard in real life! I am always putting my wire in the wrong hole! The Tinkercad program is awesome. And no wires! Hahaha. No mess!
“Amazing video, sir! Your content has inspired me to develop my own videos. I appreciate your creativity and the effort you put into making such great content!”
We have a tutorial about buzzers here: ruclips.net/video/gj-H_agfd6U/видео.htmlsi=4OlFbBHIkJ8dNUa1. Most buzzers can be driven directly by 5V and do not require a resistor.
I have a code to make blink as many LEDs as you want. In my case, with three, I have simulated a traffic light // Define the pins where the pins are connected const int ledPins[] = {11,12,13}; // To add another pin, I don't have to declare another variable. Only add the number to the array const int numLeds = sizeof(ledPins) / sizeof(ledPins[0]); // The total numberr of pins. It will be re-calculated automatically if I add another pin const int states[] = {0x1,0x0}; // 0x1 = HIGH, 0x0 = LOW const int numStates = sizeof(states)/sizeof(states[1]); // The number of states. I could replace the calculation by 2 (because allways will be two states void setup() { //I declare all the pins like output for (int i = 0; i
Thank you for this video. Since I'm new to the Arduino world i have a question.... How do you get the program you have made on the Arduino UNO board into a microcontroller used and placed on your project on another PCB...?
Hi - this is a bit more than we can explain in a RUclips comment, we recommend asking on the official Arduino forums. Very long story short, we don't have our own tutorial on it, but the Arduino board contains a extra circuitry that handles USB communication with your computer and makes uploading code very easy. If you just want to buy the bare microcontroller chip and put it on another PCB, you then need to handle that part (flashing the code to the chip) yourself. There are other things the Arduino board includes, like voltage regulation so you can power it with a 9V battery or wall adapter, that aren't included in the bare microcontroller chip, which you would need to account for when designing a separate PCB. Again we don't have our own tutorial but you should be able to find instructions online.
So I bought a RexQualis board and I am using a mac book and it's still not working for me. I followed everything, could it be board not matching the brand? Is the fact that I have to and extra wire because the macbook only has thunderbolt ports?
For two LED's could we just connect the two LED's with one resistor so that the resistor is in series with the LED's in parallel? Or is that different?
The answer is a little too complicated to explain in a RUclips comment. We just added an entire playlist about the math behind LED circuit design, we recommend you check that out: ruclips.net/p/PLlBVuTSjOrclaUU1nI3afV1jp8vj4iQUf&si=FPnWpc1Hkfmyjcfk
The power comes directly from the Arduino's I/O pins. They can provide enough power directly for small things like LEDs, but not larger things like motors.
The LED's apparent brightness can change depending on the camera settings, but like @vito8625 said, it depends on the resistor value and the amount of current through the LED. We have a new video series coming out about choosing the resistor value, so stay tuned!
I know this video old but I’m using Arduino right now and I got all my led working but 2 of them won’t blink on and off and I been stuck on what could be wrong that only one light will blink btw I’m doing a traffic light project
Hi - we can't necessarily help with your exact circuit, but our troubleshooting video might help you identify problems: ruclips.net/video/9GLaU-BCEQM/видео.htmlsi=sb0o-Ncuy2_XZL76
Thanks for not assuming that we already know the basics. what if I want to use a device that requires more current than the Arduino can provide? Thanks

Hi there, I purchased a kit from AliExpress, and I built the circuit correctly. The LED does blink every 1 second but sometimes it ''jumps'' (goes off earlier or stays on longer). I tought the problem may be in the end of my program as it is a loop, but I wrote the exact same program you did.. Any idea why does that happen?
Hi - we haven't heard of that problem before. The only thing I can think of is a loose or intermittent connection with part of the breadboard. The amount of time it takes the code to execute a loop should not change from one loop to the next. There's also a chance of a faulty I/O pin, you could try switching to a different pin and see if it's more consistent.
Hello!! Great job!! I am rookey and I have a question. I have Arduino Nano. Where can I put the Red cable? Because nano is smaller than Uno and does not have the Arduino 12 port(pinMode12) .
u can change the port 12 to some other port (must be digital) and change the port number in the code, so that all places with 12 are the other port you are using
i was having a problem with making this kind of circuit. i just realized i had put the jumper wires on the wrong area before i knew this. 😭😭😭😭LIKE THIS COMMENT IF THAT HAPPENED TO YOU
This series has really helped me to learn how arduinos worked straightforward and simple thank you
GREAT breadboard demo. Love this series
I purchased a kit through a workshop at my school and this one helped me a lot to do it in the comfort of my house. 🤩Thank you!
Thank you for this awesome tutorial, as a beginner this tutorial series is gold. Please continue making such great tutorials.
Thanks - we just published one and have another one coming shortly - stay tuned!

Im a student learning arduino & tinkercad ! ! Thank you so much for your explanations, they surely help!❤
You're welcome! This is an entire playlist so make sure you check out the rest of the videos too.
It is my first time that working on Arduino is too much easy thank you very much.
never seen the inside of a BB ... well worth seeing!!! Thank you.
Awesome video, keep going bro, this helped me learn how to use Arduino
Great tutorial man I like it ❤💯
These Arduino tuts are great!
Thanks - stay tuned, we have more coming!
My led is blinking thank you sir 😊
“Amazing video, sir! Your content has inspired me to develop my own videos. I appreciate your creativity and the effort you put into making such great content!”
Chanced on your channel and must say , excellent explanation. Thanks
Wonderfully explained...simple and clear. Thank you
Thank you so much for teaching me, this was my very first project
great tutorial, Thank you❤
excellent explanation
can I replace the led with an active buzzer. If yes, how much ohms does my resistor need
We have a tutorial about buzzers here: ruclips.net/video/gj-H_agfd6U/видео.htmlsi=4OlFbBHIkJ8dNUa1. Most buzzers can be driven directly by 5V and do not require a resistor.
Do I need a resistor if I use weak batteries
Works well thx ❤
very helpful for my grandson😃😁
“ you might’ve built your circuit like this” Ey yo mine don’t look like that 😂 but it worked! The code first try had them blinking separate fixed it
how much time it takes ?bcuz in using a ATMega328PB is it okay ?
I have a code to make blink as many LEDs as you want. In my case, with three, I have simulated a traffic light
// Define the pins where the pins are connected
const int ledPins[] = {11,12,13}; // To add another pin, I don't have to declare another variable. Only add the number to the array
const int numLeds = sizeof(ledPins) / sizeof(ledPins[0]); // The total numberr of pins. It will be re-calculated automatically if I add another pin
const int states[] = {0x1,0x0}; // 0x1 = HIGH, 0x0 = LOW
const int numStates = sizeof(states)/sizeof(states[1]); // The number of states. I could replace the calculation by 2 (because allways will be two states
void setup() {
//I declare all the pins like output
for (int i = 0; i
Thanksss man
does it matter which side do i put the led, like which positive and which negative?
Yes - LEDs are polar and current will only flow through them in one direction. If your LED is not lighting up, try flipping it around.
Hello, I am just wondering, how to make the leg of the LED in the tinkercad more wider?
Hi - you can't adjust the LEDs themselves in Tinkercad, but you can attach jumper wires to the legs of the LEDs.
@@Science.Buddies Thank you so much for answering

Thank you so much for your answer. I understand what you mean and I will find a Arduino forum...
10:39 I actually ran out of male wires so I used common sense and wired it at the same row, I'll take that as a score
Hello! What is the resistor that you used here?
That is a 220 ohm resistor. We have an upcoming video series about choosing the proper resistors for LEDs, stay tuned!
So I bought a RexQualis board and I am using a mac book and it's still not working for me. I followed everything, could it be board not matching the brand? Is the fact that I have to and extra wire because the macbook only has thunderbolt ports?

I still don't get it
Where did you get the power from if you didn't use any jumper wire to connect 5V pin to breadboard?
The power comes directly from the Arduino's I/O pins. They can provide enough power directly for small things like LEDs, but not larger things like motors.
Thanks for the information
How do I attach a battery so I don’t have to plug it into my laptop all the time
How did you make the red led that bright? When i tried this it was very dim
Your resistor may be a higher value. Also LEDs can vary on their brightness specs
The LED's apparent brightness can change depending on the camera settings, but like @vito8625 said, it depends on the resistor value and the amount of current through the LED. We have a new video series coming out about choosing the resistor value, so stay tuned!
Thanks!
I used a 220 ohm resistor so i'll try with a lower resistance resistor
I know this video old but I’m using Arduino right now and I got all my led working but 2 of them won’t blink on and off and I been stuck on what could be wrong that only one light will blink btw I’m doing a traffic light project

Hey I didn't connect it like you expected in the question but I still got it to work. What do I do?
Hi - that's OK, there is frequently more than one "correct" way to wire the circuit.
@@Science.Buddies okay. Thank you for a great video

Because nano is smaller than Uno and does not have the Arduino 12 port(pinMode12) .
Hi - all our tutorials are for the UNO, so you may have better luck getting answers to your questions on the official Arduino forums.
u can change the port 12 to some other port (must be digital) and change the port number in the code, so that all places with 12 are the other port you are using
@@aksvinssthank you! It works!
We all want to know what happened to the blown up hole on the left at 2:12 🤣
can you do Long and Short LED Blink
Yes
You change the second delay
do for me pixel5
