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. 👍
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!
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

We have a tutorial about buzzers here: th-cam.com/video/gj-H_agfd6U/w-d-xo.htmlsi=4OlFbBHIkJ8dNUa1. Most buzzers can be driven directly by 5V and do not require a resistor.
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 TH-cam 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.
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
Check out our full playlist, particularly #16 about controlling motors and #19 about power: th-cam.com/play/PLlBVuTSjOrclb0iCMSRpS_H1lSrlSVeEm.html&si=opGDZTZlbl7VYF6t
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?
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.
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 TH-cam comment. We just added an entire playlist about the math behind LED circuit design, we recommend you check that out: th-cam.com/play/PLlBVuTSjOrclaUU1nI3afV1jp8vj4iQUf.html&si=FPnWpc1Hkfmyjcfk
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.
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: th-cam.com/video/9GLaU-BCEQM/w-d-xo.htmlsi=sb0o-Ncuy2_XZL76
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!
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

This series has really helped me to learn how arduinos worked straightforward and simple thank you
It is my first time that working on Arduino is too much easy thank you very much.
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!

thanks man this helped alot and now i have made 5 lights with it
can I replace the led with an active buzzer. If yes, how much ohms does my resistor need

These Arduino tuts are great!
Thanks - stay tuned, we have more coming!
Awesome video, keep going bro, this helped me learn how to use Arduino
Chanced on your channel and must say , excellent explanation. Thanks

Thank you so much for your answer. I understand what you mean and I will find a Arduino forum...
Great tutorial man I like it ❤💯
Wonderfully explained...simple and clear. Thank you
very helpful for my grandson😃😁
excellent explanation
“ 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
Thank you so much for teaching me, this was my very first project

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.
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?
Hi - we recommend asking on the official Arduino forums for help with your problem.
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
great tutorial, Thank you❤
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
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
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?

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!
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).

Same! We just did a manual traffic light!😮
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
Thanksss man
how much time it takes ?bcuz in using a ATMega328PB is it okay ?
unlimited
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) .
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!
can you do Long and Short LED Blink
Yes
You change the second delay
do for me pixel5
great tutorial, Thank you❤
