Toy Records Play Music Using Changing Colors [Video]

A device called Color Play uses a light frequency sensors to create sounds.

A project by students from the Interactive Telecommunications Program at New York University explores the relationship between color and sound. Created by Natasha Dzurny and Louie Foo, Color Play is a device that looks like a record player but plays music from a color wheel instead of a music record.

The color wheel is made of plastic wedges in different colors and widths. Different colors represent different pitches and different widths represent different rhythms. The colored wedges can be rearranged any way you want on the removable tray and the speed of the spin can be controlled through a knob.

The key to how the device works lies in the color sensor made from a photocell and an RGB LED. Colors absorb and reflect different amounts of light and the sensor shines green, red, and blue light then records the amount of light that returns. The device makes a sound based on the values obtained by the sensor.
