Hi all,

I wish to build a device that will turn on an appliance upon
recieving a burst from an IR universal remote control.  The device
would have to recieve the burst from the remote, then turn on AC to
the appliance and vice-versa.

I have seen the IR receiver modules in Digi-key and I'm not sure if
they are what I want for this project or not.

What "carrier frequency" should I use?  There is 32.7, 36, and 40
Khz.  Does it matter?  Do some brands use different "carrier
frequencies"?

What comes out of the IR reciever?  Serial data?  or just a pulse
train directly derived from the IR remote's output?  In other words,
how do I interface to it?

Does anybody know the answers to these questions or where I can find
a resource that might describe IR remote technology in mor detail?

Thanks,

Shawn Ellis
