[Alan] has been working on driving this WS2811 LED module with an AVR microcontroller. It may look like a standard six-pin RGB LED but it actually contains both an LED module and a microcontroller … ...

Timing is everything and that’s why most communication protocols require a very accurate clock source. The WS2811 LED strip controllers are no different. But [Danny] figured out a way to driv… ...

On the other hand, commanding a WS2811 device via its serial control bus is not a straightforward task. Part of this is because it uses a single combined clock and data line to ripple the instructions ...
