I’ve implemented a simple IR universal remote that will record an IR code and retransmit it on demand as an example for my IR library. Handling IR codes is a bit more complex than it might seem, as many protocols require more than simply recording and playing back the signal.
To use the universal remote, simply point your remote control at the IR module and press a button on the remote control. Then press the Arduino button whenever you want to retransmit the code. My example only supports a single code at a time, but can be easily extended to support multiple codes.
