Awkward Musical Instrument Thoughts…

I want my instrument to be played in a way that you don’t automatically think of so no strumming, blowing, drumming, etc. I looked at a few different ideas and decided on using a PING ultrasonic distance sensor. With this sensor, the different tones will be determined by how far an object is away from the sensor and I am using a lot of code from this page for this project. Here is a video showing how this sensor works!
