Using an Infra-Red Remote Control with your Raspberry Pi

It is often useful to control robots remotely. An easy way to add additional input is to make use of an IR (infra-red) receiver and a standard remote control. Fortunately, the receiver is well supported.

We will use a module called LIRC to capture and decode IR signals from a standard remote control.

Getting Ready

LIRC supports many types of IR detectors, such as Energenie's PiMote IR board; however, since we only need to receive IR signals, we can use a simple (TSOP38238) IR detector.

The three pins of the TSOP38238 IR Receiver can fit directly onto the Raspberry Pi header
