The WS2812 is controlled with a wierd single line protocol that's really efficient but very sensitive to timing. The whole thing works off of PWM signals on the signal wire, and there is no clock synchronization. Basically every LED receives a 24 bit color value (in RGB or GRB or whatever format is appropriate), then there's a pause, then the next value is sent for the next LED. If you've got 8 LEDs in series, you get 8 24 bit values, in order.

<-- more LED values, or a
