I would start off by looking at the TSOP1738 data sheet.
Then using that data jump to the TSAL6200 data sheet.

Almost no hardware needed - check my PIC tutorials for the hardware I use, the same would obviously work just the same on an AVR - the modulation is all in the software, and dead simple to do.

You can take a look at Basic IR Communications and IR Beam Break Test Bed for simple examples.
