# Node-RED NeoPixel Control

Day 88 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

Drive NeoPixel colors from Node-RED dashboard widgets over MQTT. Lighting scenes as flowcharts.

## How it works

Color pickers and sliders on a Node-RED dashboard publish MQTT messages carrying RGB values; the Pico 2W parses them into NeoPixel colors. Lighting scenes become flowcharts you can rearrange — automation as visual programming.

## What you'll learn

- Dashboard widget design
- Color commands over MQTT
- Scene-based lighting
- Visual automation
