Need help with simple IR remote circuit

  1. Can someone recommend a simple IR remote receiver circuit that can
    understand about 20 commands.

    I am looking for a simple circuit, or a device that I can cannibalize. The
    outputs are going to drive bi-directional switches.

    The IR signals will ultimately be transmitted by a learning remote. I would
    prefer not to have to build the initial transmitter if I could use a
    pre-existing remote unless the transmitter circuit is very simple.

    Thanks for your help.

    Check the ELM339 - Infrared Remote Control
    from Elm. It will control 3 devices:

    Otherwise I see a lot of tossed out VCRs and remotes in the garbage
    and for a few bucks at garage sales. You could hack the remote board
    directly or take the IR sensor out of the VCR and use the remote to
    digital words to a PIC you programmed. Which I usually avoid.
    a lot of IR info at:

    Good luck
