David Madison b541a2085a Added WS2812B Arduino code 
The initial modifications to the Adalight code to incorporate the
FastLED library and work with WS2812B LEDs were done by James Bruce
(@jamesabruce). I can't find a way to do a pull request on a Gist, so
I'm copying his code in full here.

Synopsis

This is the standard Adalight library, modified to work with 3-pin WS2812B LED strips (2016-era Adafruit NeoPixels). The Arduino code has been modified to use the FastLED library.

In addition to ambilight setups, the protocol can be used to stream any color data from a computer to a WS2812B strip (data rate limited by serial throughput).

Configuration

Open the WS2812B file in the Arduino IDE and edit the definitions at the top for your setup. Specifically:

  • Number of LEDs
  • LED data pin
  • LED grounding pin (optional)
  • Brightness
  • Serial speed

Upload to your Arduino and use a corresponding PC application to stream color data. The Processing files are included, though I would recommend using Patrick Siegler's (@psieg) fork of Lightpacks's Prismatik, which you can find here.

Tutorial

If you'd like you can follow Adafruit's tutorial, which is fairly comprehensive for the WS2801 they use but is otherwise out of date. You can find the tutorial here:
