# NeoPixel Web Controller

Day 80 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

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
