A very good introduction to the RGB addressable LEDS.
I would say very useful for beginners and old hats like me.
Well done. and well presented.

Thanks for this! Got myself a pack of LED diodes which I thought was just a simple 4 pin RGB LED, which turned out to be a WS2811 8mm diode, was extremely confusing why it wasn't working when I followed other simple RGB led tutorials, and got to this which makes so much more sense! (and so much easier given I can control multiple of those diodes just by plugging them into a breadboard..!

I watched until 5:05, then wrote this comment and grabbed the LED strip so I can do cool visuals on wall art...



Thank You!!

Hi Dejan, your LED projects are fascinating. It would be great if you could do an in-depth tutorial specifically on the hardware and then the coding needed for first an LED cube 8 x 8 x 8 and then the holy grail of all electronic hobbyist- The RGB LED CUBE , I think that tens of thousands of electronic enthusiast like myself would benefit from such an educational video- actually the subject matter is so complex in my opinion you would need several videos- maybe :-)
Thank You So Much Jim

I love these collaborations - really gives each of you more scope.

A truly awesome video, thank you for sharing. I came to learn about LEDs and got a bonus introduction into the art of Bluetooth and creating an android app. Thank you!

Your effort is appreciated. Your English and presentation is perfect. Your voice is sincere. Your video is truly awesome. Thank you very much for your time and consideration.

Thank you. This was enough to jump start me with simple Arduino programming.

Whoa!! This was the first arduino dyi video I saw 2yrs ago and now I'm ready for code

very good introduction to the RGB addressable LEDS. Thank you

[FrancescoCositore]

Great tutorial! Very useful!😉😉 just a note, in the project you should add some shift register in order to minimise the number of Arduino analog input so you will be able to use Arduino UNO board instead Arduino MEGA in the project.

Very good video. One day i went to some friends house and he showed me an adressable led strip. I looked at the strip closer but did not see any shift registers or driver ic. Only now i realised to investigate if the driver is inside the led chip :D

Hi. i just finished the coffee table. First of all: awesome project!
I wanted to comment that when i turned on all worked except controling with the app. I don't know much about this stuff but after doing some searching i found that the hc05 module´s default baud rate was 9600. So i changed that in the arduino code and voilà. It works perfect. In case someone is having the same issue ;)

[AzzYung]

This is the LED Ive been looking for! I plan to switch out my LED as my old ones died out on my keyboard. Awesome video!

I had to program 4 of them with an FPGA for college ELEC, so difficult but quite the digital logic exercise.

If you wish to integrate the pixels into a DMX512 environment, there are many DMX to WS2811 converters as well as streaming ACN to WS2811. WS2812 uses the same protocol as WS2811, but simply has the chip built into the pixel.

A DMX to WS2811 converter is limited to the 512 channel DMX limit, but with a multi universe E1.31 to WS2811 interface (sometimes called a controller) it is possible to send more than 512 DMX channels to one string of pixels by combining multi universes of 510 channels. With 3 channels used per pixel, this is 170 pixels per DMX universe of 510 channels.

You make it look so easy. Brilliant sir!

[SuperRossparker]

with those libraries the CHSV params are way easier to use for anyone wondering. it uses hue, saturation and value. plus with the fastled lib it auto loops so you can run a single loop for easy colour cycling.

Thankyou for this detailed explaination
