I have done a simple infrared remote control receiver with RS232 ascii output. It can be used for developing remote controls on a PC using the serial port. In practice, the infrared bursts are converted in ascii characters and sent to the RS232 port. The downloadable ZIP file contains the schematic diagram, the printed circuit board, the components disposition and the object file to write into the ATMEL ATtiny2313 microcontroller.
