This repository contains a fork of Zulko's original "Pianoputer" which expects to find a RaspberryPi hooked up to an ultrasonic distance sensor (an HC-SR04), to work like a theremin.
From Zulko's original post:
"To play you first need to install Python, and the Python libraries Numpy, Scipy and Pygame. Agreed, the dependencies are a little heavy.
Then you just unzip everything in a folder and run this line:
python pianoputer.py --wav clarinet-middle-c.wav
