How To Program WS2812 LEDs with FastLED and an Arduino

In this video, I explain how to write your own programs that interact with WS2812B LED's using the FastLED library. I go over both preset colour schemes, and how to create your own colours using both RGB values or HSV values, and send them over to the LEDs.

IMPORTANT:
This video is part 2 of 2 of my Introduction to Addressable LEDs series. Part 1 focuses on setting up the hardware and software, and running some demos to get up and running.

Components used:
- Generic WS2812B 30 LED/m strip
- Generic Arduino Uno with Atmel 328p
- FastLED library

I won't add any links for purchasing, this video is not sponsored and all components were supplied by myself, but make sure you choose a reputable source for parts!

If there are any mistakes or bad practices I mentioned in the video, please leave a comment and I'll try to pin a compilation of updates.

Production rants/remarks:
- I know the 2 mics I used have different EQ's, it's really hard for me to match it, so I won't.
- I had to color correct all the camera shots, sry if I forgot anything.

Wow so nice... Can make a vedio on random color choosing ws2812b

As a guy who just want to do a specific project, that was just the perfect video that I was looking for.
Quick question... How to fade in/out the 2 leds that moving in the strip?

Thank you!! Keep your good work!

How can i control 72 leds if I only want the 64leds in the middle to do rainbow running and the 4 front leds and 4 end leds to blink red and blue?

HI, will this work with any led light strip manufacturer..not sure what mine is

Hello Tony, thanks for the video, which was very informative as I am creating a map project that gets info from an external computer, and I need to indicate 110 locations on a map with addressable LED`s run by an Arduino Uno. so my question is, would I have to tell the Arduino which map location refers to which piece of serial data? For example, would i need to put 110 different serial codes into Arduino memory to select whatever LED it refers to? Thanks from Russell.

Thanks for sharing, it would be great if you do another tutorial on more random effects, that was fun watching and learning about effects, Also, is the FastLED library in Arduino IDE something like a Java Script behind Html for example,
Thanks

Please!

Only do tutorials if you have some knowledge of programming.

Hello tony...can i contact you through email? I would like to ask you something regarding my project...from the 🇵🇭🇵🇭🇵🇭here...
