I finally built a small project that allowed me to use WLED for the first time. I used an ESP8266 board and a bunch of WS2812B LEDs to complete it.
This WLED guide will give you an overview of what you need to get started. Find out which microcontroller and LED strip is best, and how to wire them.
WLED only does one thing: It controls NeoPixel LEDs (WS2812B, WS2811, SK6812). And it is class leading at what it does.
