AVR-Based Serial Port IR Receiver
http://www.electronics-lab.com/ blog/ ?p=1949This is a simple IR receiver circuit which plugs into a serial port of a computer. Althrought, there are many other circuits of this kind, and most of them are even simpler, but this circuit has two major advantages: (1) it uses an Atmel AVR RISC microcontroller (an AT90S2313) instead of the usual PIC microcontroller and (2) it uses a Maxim MAX232 for the generation of valid RS232 levels.
