The Infrared Receiver is used to receive infrared signals and also used for remote control detection. There is a IR detector on the Infrared Receiver which is particularly sensitive to the infrared signal,and it can receive the infrared signal very swiftly .The Infrared Receiver can receive signals well within 10 meters. We suggest you using the Infrared Remote Control or any infrared emitter to make your own remote control projects. You can download the Starter Kit Guidebook experiment 13 - infrared remote control and related source code to learn how to use this module.
