Android Things demo project which controls WS2812B LED strip. Uses SPI bus for communication with strip. Can be used as a library for other projects.

![](demo.gif?raw=true)

For Raspberry Pi 3 connect strips's D_IN to GPIO10(SPI0_MOSI).

# How it works

It uses blocks of 4 bits in SPI transmission to generate one bit of WS2812B

protocol. Diagram below explains such usage of SPI.
