WS2812D LED 8mm RGB WS2811 LEDs There is a new addition to the popular WS2812 family of RGB LEDs with integrated controller: A 8mm through hole version. Right now they seem to be in pilot production stage

========================================= This code provides some subroutines to drive one or more WS2812 LEDs (RGB LEDs with built-in WS2811 controller). Because the timing of the output signal is different from the standard serial protocls (RS232, SPI) supported natively by the µC, it has to be generated
