Sound Reactive Paper Lanterns with LedFx

Create an array of paper lanterns and control them with sound.

This guide uses a Feather ESP32 V2 loaded with the free, open source WLED software.

WLED runs on the Feather, using WiFi to allow you to control the lights with your phone, PC, or any wifi-enabled device. This is a lot of fun, and will make for a beautiful piece of light art in your space that’s easy to control and program with your phone.

But this guide goes further! WLED interfaces seamlessly with LEDFx, an open-source program that runs on your computer to capture and analyze sound, either from your music player or from your computer’s microphone. It takes the sound and translates it into light effects, so your lights can run sound-reactive animations over WiFi without needing to add a physical microphone.
