Here’s another interesting CheerLight project — a simple and effective RasPi + Arduino project that uses a ping pong ball as a collector and diffuser that permits a tremendously wide range of colors from the CheerLight feed. Via CheerLights:
Mike created a really simple, but powerful CheerLights display using an RGB LED to show colors, an Arduino Uno to control the LED, and a Raspberry Pi for network connectivity. The RGB LED in this project requires pulse width modulation (PWM) to set the color. PWM allows you to blend the colors (Red, Green, and Blue) to make other colors such as Orange. The ping-pong ball blends the separate colors into one seamless color. The Raspberry Pi is used for network connectivity and reads in the latest CheerLights colors from the CheerLights API.
Visit CheerlightsPi on GitHub for the details and Raspberry Pi and Arduino source code.
