  1. Hi, i want help in building an IR receiver circuit that can receive
    signals from 20-25 feet of an IR transmitter. Please help me in
    identifying the type and range of components to be used in such a
    circuit.

    This receiver is to be connected with a digital clock that can respond
    to the signals from the IR transmitter and hence change time/date
    accordingly.
     
  2. Go to Radio Shack and save time:
    38kHz Infrared (IR) Receiver Module
    Model: 276-640 | Catalog #: 276-640
    Great for experimental projects and building your own remote control.
    Low-voltage. Elliptical lens h...

  3. Well if you're going to do that, you might as well just wait for a TV
    set or cable converter on the sidewalk waiting for the garbage truck,
    and pull the circuitry from it. Often, it is indeed in the form of
    a discernible module. And the Radio Shack module is basically the
    same thing, the IR receptor and an IC amplifier.

    Of course, neither solution does it all. All you get is a recovery
    of the modulation on the transmitter, and from there one has to decode
    the digital data and then use it to do actual switching. The module
    takes care of what it does, but that's all.
