Serial Port IR Receiver Using AVR
Another cool microcontroller project created by Klaus Stock. He said, this is a simple IR receiver circuit which plugs into a serial port of a computer. 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.
Advantage 1 is, of course, only valid for all those AVR addicts which have this device (and the corresponding programmer) ready at hand and don’t care about PICs and PIC programmers. Advantage 2 comes into play if the IR receiver has to placed at a great distance from the computer; the MAX232 is more likely to deliver valid signals over bigger distances than cheaper solutions.
