Synopsis

This is the Adalight library with the Arduino code modified to use FastLED (fastled.io). This expands Adalight to, in theory, work with any supported FastLED strip including WS2812B (aka Adafruit NeoPixels).

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

Configuration

Open the LEDstream_FastLED file in the Arduino IDE and edit the setting definitions at the top for your setup. These include:

  • Number of LEDs
  • LED data pin
  • Max brightness
  • LED type
  • LED color order
  • Serial speed
  • Serial timeout length

There are also optional settings to configure a dedicated ground pin and to put the Arduino into a "calibration" mode, where all LED colors match the first LED.

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.

Issues and LED-types

I've only tested the code with the WS2812B strips I have on hand, but so far it performs flawlessly. If you find an issue with the code or can confirm that it works with another chipset, please let me know!
