WS2812B RGB LED strip driving code
This code is meant for 16MHz Arduino, but should work on any 16MHz AVR. It is in plain C, not the Arduino language.
All you need is ws_driver.c and ws_driver.h, and config.c where you define the port / pin information.
Connection
Digital pin 8 on Arduino (PB0) is connected via a 200-500 R to WS2812B data input. In parallel to the LED strip is a 500-1000 uF capacitor that takes care of smoothening the power supply. Without the cap, the LEDs will flicker.
It is recommended to use stronger power supply for the LED strip, a 30-led one takes around to 1A when fully powered.
