Скачать или смотреть Infrared (IR) Control with Circuit Playground & MakeCode

The latest Circuit Playground board, the Adafruit Circuit Playground Express comes equipped with an onboard IR transmitter and receiver! This can be used to communicate with TVs and other household devices. You can also use infrared remote controls to control your Circuit Playground Express. You can use another Circuit Playground Express as a remote to control your CPX, and you can even send simple messages between Circuit Playgrounds. By measuring the raw reflected IR light bouncing off of nearby objects you can make a simple proximity sensor!

For this project, we will be utilizing the infrared transmitter and receiver to control two different light animations on our Circuit Playground Express. We will put the same program on two Circuit Playgrounds, so one can act as both a remote and a receiver. The transmit and receive on the Circuit Playground Express works reliably up to three meters. If you are only receiving signals with the Circuit Playground and controlling using a TV remote, you should have longer range.
