Yesterday I bought this board from the scrap bin at All Electronics: http://www.flickr.com/photos/chrisjelledge/

What I know about this board is that it has a IR receiver with the following specs:



  _________  Infrared sensor module
  |     _      |  Numbers printed on the top:
  |   |  |    |  TK69   931
  |   |  |    |  TSOP  1738
  |   |  |    |

   |   |       |
   |   |       |
   |   |       |
Gnd  |      Output
      +5V

There is a 12 pin right angle pin header on the board.

Is there any way I can use this to make a IR Power switch?

Did you try a Google search for 'TSOP  1738' ?

Yep, that is how I got this info. What I really want to do is have  3 sets of 22 led's powered by a 9 volt battery. Each set will bes used for light painting so all the receiver is really doing is switching between the sets when signaled by a Apple Remote. If this is not possible I will use the Ir switch to turn the battery on and off, and manually switch between sets.

Just google for "Arduino IR library". You'll find plenty of examples on how to use it.

Your IR receiver doesn't appear to be specific to any protocol other than requiring a 38Khz modulation.

Curiously the picture of your board states it is 56Khz modulation, but the datasheet says 38Khz.
