[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 ... the hardware is how each pixel is addressed.

Addressable LED is an ... you to control the color and brightness of each LED independently. The combined LED/driver chip on the LED is the extremely compact WS2812B – an improved WS2811 LED driver ...

Individually addressable RGB LEDs at a low price. Just attach an Arduino, load the demo code ... With 4k of RAM, you can control 42 LEDs. That’s the same amount of RAM that the Apollo Guidance ...

The second LED pixel grabs RGB sequence #2, displays it, and so on until the end of the chain is reached (Fig.4). Fig.4: Programming WS2811 LED drivers requires the 24-bit color code for each pixel to ...
