Synopsis

This is the standard Adalight library, modified to work with the FastLED library (fastled.io) and 3-pin WS2812B LED strips (2016-era Adafruit NeoPixels).

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
• Serial timeout length

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you'd like you can follow Adafruit's tutorial, which is fairly comprehensive for the WS2801 they use but is otherwise out of date.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