Node-RED NeoPixel Control
Cloud · Board: Pi Pico · Day 88 of 100
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
