Arduino universal remote: record and playback IR signals

Irrecord
Ken writes

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.

  1. This is like the thing Steve Wozniak made with his company (Cloud something)…

    Still awesome!

  2. Finally… Kudos! 😀

  3. I’ve got a rc tank that uses IR.
    I “fire” into the receiver and am hoping the transmitter will return fire.

    Doesn’t seem to be any of the standard protocols.
    Your IR Record only seems to store a few raw values…playback does not trigger the desired effect.

    Could you modify your IR record to record more values.
    results->rawlen is not big enough.
