Want to wow the audience at your next gig? Light up those parties with a 3D Printed, LED sound reactive microphone flag. This project uses a microphone sensor to illuminate a custom 3d printed mic flag. You can design yours, or use our STLs to print and make your own!
This guide was written for the 'original' Gemma board, but can be done with either the original or M0 Gemma. We recommend the Gemma M0 as it is easier to use and is more compatible with modern computers!
