Description
Sound Reactive Guitar Strap
This project uses the Circuit Playground Express (CPE) board by Adafruit and its built-in microphone to sense sound. It reacts to sound/music intensity by lighting up a proportional number of LEDs, first onboard the CPE and then extending to attached addressable WS2812B devices.
The video above shows this implemented with PCBs recycled from a previous macro pad project and attached to a guitar strap. Each board is soldered together in order to pass signals/power/ground along to the next, allowing for a neat VU meter effect.
In the second "Ez-build" iteration of this project, I substituted in an addressable LED strip for the repurposed PCBs. In theory this device could be made without any soldering, just alligator clips, but you might want to solder things on anyway.
