CheerlightsPi = Arduino + Raspberry Pi + CheerLights API #raspi #piday
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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
