The Arduino-powered Color Musical Instrument

In order to create a fun activity for children, Instructables member poblock1982 came up with the following device that demonstrates sounds and colors - and also to help start conversations about the physics of colors. 

Based around an Arduino Nano-compatible board, the device uses a color sensor to report on the color on a wheel that rotates around under the sensor.

Each color is assigned a tune in the Arduino firmware. so as the color wheel rotates the device can play a tune. A quick demonstration is shown in the video below:

This is a fun project that is also quite easy to make. For more information, visit the project instructables page.  

To help you get started with your own version, PMD Way offers Arduino Nano-compatible boards, color sensors, continuous servos, hardware and more.
