Ultrasonic Pi Piano

I created this project in conjunction with The Gizmo Dojo (the Broomfield, CO maker space). The idea is pretty simple - using ultrasonic sensors as input and translating distance measurements into MIDI notes that are then played via a software synthesizer on the Raspberry Pi.

This project has been featured on hackaday.ioAdafruit Blog, and The Raspberry Pi Foundation's Blog. I have also written up a detailed instructable on how to build this.

Here's a video showing the final product.
