This code lets you use your Arduino for controlling a 3 pin addressable LED strip, originally designed to work with an RGB computer fan where the strip is a ring.

The most fascinating project you can build is something with a bunch of blinky hypnotic LEDs, and the easiest way to build this is with a bunch of individually addressable RGB LEDs. [Ole] has a ...

Individually addressable RGB LEDs like Neopixels, WS2812s, and WS2811s are the defacto standard for making blinkey glowey projects. To build a very bright display, you need a lot of them ...
