NEW GUIDE: IR Receive and Transmit with Circuit Playground Express
Use CircuitPython to send and receive infrared signals using the Circuit Playground Express!
The Circuit Playground Express is an amazing little board with tons of sensors and things built in, including an infrared transmitter and an infrared receiver. This guide will show you how to use CircuitPython to send simple messages between two Circuit Playground Expresses using infrared! We start by having you test your CPX with a remote to show receiving IR signals. Then we provide an example that transmits IR signals from the CPX. IR signals can be used as an input to trigger all sorts of things. We show you how to take those signals and use them to turn on LEDs and make a sound on another Circuit Playground Express!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
