Turns on LED upon receiving IR signal

[DutCampos]

Hi everyone, I'm working on what I think is a fairly simple project. However, I have no previous experience with electronics, so help would be greatly appreciated.

I have to build two pairs of circuits: an IR transmitter and an IR receiver for each (let's call them pair A and pair B). The IR receiver needs to receive a signal from the transmitter and, upon receiving it, turn on a visible light LED (color doesn't really matter).

The two catches are: 1) The pairs need to be "unique", meaning that Receiver A can't light up upon receivipng a signal from transmitter B (I think this means I need to modulate the transmitter's carrier frequency). And 2) I need them to be as small as I can possibly make it, especially the receiver.

Here are some ideas, from what I've read:

Feel free to disregard all of this if it's stupid or if you have a better idea!!

a) The receiver would use something like this (https://www.sparkfun.com/datasheets/Sensors/Infrared/tsop382.pdf) of two different carrier frequencies. I would use that to light up a regular LED with a small button-cell battery.
b) I could use this (https://www.sparkfun.com/datasheets/Components/SMD/DS1077.pdf) to modulate the carrier frequency on the transmitter, maybe?
c) Build the receiver circuit on this protoboard (https://www.sparkfun.com/products/8886)

Ask me if you have any questions and thank you for your help!

Place a large electrolytic across the tssop device if you use one, they are sensitive to power supply noise.

Thank you! Now what would I use as a transmitter? I'm not sure how to modulate the frequency from the IR LED

Here is the matching transmitter. ATTACHED

There is also a 7 output receiver.

A processor based solution is the way to go, there are PIC examples in my tutorials which do pretty well what you want, and could VERY easily be modified to do exactly what you want.

The custom chips mentioned above are probably just pre-programmed processors?.
