RPi4 LED Controller
An MQTT-controlled LED strip animation system, running the lights around a 3D printer.
RustMQTTEmbeddedIoT
Controls an LED strip wrapped around a 3D printer, running on a Raspberry Pi 4. It listens on an MQTT channel for commands and plays back animations on request, so lighting state (idle, printing, error, done) can be driven from whatever else is watching the printer without touching the controller itself.
Finished and in daily use, with room to grow the animation set.
