Gemma-powered neopixel sound reactive drums

Screen_Shot_2014-08-27_at_9.54.00_PM.png

This tutorial from Adafruit shows how to create a custom interactive drum set that lights up with sound. It uses a mic amp sensor that is connected to a miniature Arduino Gemma board to detect when the instrument is being hit by the sticks. Neopixels then illuminate into a range of colors creating a beautifully synced up music presentation.

The container that houses the electronics is 3D printed. The entire circuit is integrated into the snare, mid-tom, hi-tom and a drum kick. All the code and step-by-step instructions can be found on Adafruit’s website.
