- Proximity Theremin
This semester I took a Microcontrollers Course where I learned about assembly language and C and about the properties and functions of a microcontroller. For my final project I made two theremins using Arduino. Above is the link to my report explaining the process, code and materials behind each theremin.
A theremin is an electronic musical instrument where the performer does not touch the instrument but still somehow controls the notes emitted. The first approach I took was using a photocell to sense light intensity and turn that into the notes produced. This was inspired from the Adafruit Lessons https://learn.adafruit.com/adafruit-arduino-lesson-10-making-sounds/arduino-code
My second approach involved using an Ultrasonic Range Finder that used the distance to determine the pitch produced and used a timer as the oscillator to create the audio signal. This was inspired from a blog I found while searching different ways to create theremins. http://blog.jacobean.net/?p=766
