NeoPixel Web Controller
Lighting · Board: Pi Pico · Day 80 of 100
Paint a WS2812B 8-LED ring from any browser via the Pico 2W. Addressable color, wirelessly.
How it works
Color commands from any browser reach the Pico 2W over Wi-Fi, which translates them into the precise timed signal the WS2812B ring demands. Each of the eight LEDs can show its own color and brightness — addressable light, wirelessly painted.
What you'll learn
- Addressable LED protocol
- NeoPixel timing
- Per-LED color control
- Browser-to-light pipeline
