Alfred73 has made some interesting projects. This one is the Six Channel IR Remote Control System which uses a customized remote control to take control of some normal appliances. It is based on the older 16F84 PIC but should be simple to convert to work with the 16F628A. Code and the schematic are provided on the site.

“This project is a remote control system based on a pic and an universal remote controller for TV, named SIMPLEX.

The IR signal of a specific remote controller is received from an IC receiver(SFH 505 or similar ) and sent to the pic, the inside program decodes the algorithm and switches 6 output ports and the corresponding relays .You can use it to control 6 appliances of your room such as lamp, radio, Hi-Fi , TV , computer and so on .The range is great about 10 meters”
