The main difference when using this method is that the IR signal is not inverted as it would normally be when using a more common modulated IR receiver module. All of the Arduino code you need to ...

How to connect the TSOP4838 to an Arduino to read the transmitted codes By using a cheap integrated IR receiver/decoder device (the venerable TSOP4838), most of the hard work is done for you!

The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared emitter (IRED) is available for changing the hardware as an IR encoder.
