A creator built an audio-reactive LED display inspired by phyllotaxis, the spiral pattern found in sunflowers. Using the golden ratio to generate point clouds, they designed and 3D-printed Voronoi cells, soldered 89 addressable LEDs, and programmed shader-style animations on an STM32 microcontroller.
WLED is an open-source ESP32 webserver project for controlling NeoPixel and other LED strips with over 100 effects, modern UI, and support for multiple control interfaces including mobile apps, MQTT, voice control, and Home Assistant integration.
