Infrared Remote Control Converter (Arduino Uno)

1. Description

This project shows how to build an infrared remote control (IR RC) converter that allows emulating an IR remote control (emulated IR RC) using a different one (physical IR RC). The basic principle is the following: IR codes sent by the physical IR RC are intercepted by an IR receiver, translated into the physical IR RC corresponding codes and sent through an IR transmitter. The translation table that maps the physical to emulated IR RC codes is permanently stored in the microcontroller’s internal EEPROM; it can be easily (re)initialized by putting the system in setup mode (hardware interrupt generated by a button press).

Difficulty level: advanced.
