PIC Room Timer

The purpose of this electronic project is to present a device that is useful and at the same time demonstrate to the beginner many features involved in programming the PIC. Some of the topics included are:

* Simple use of MPASM assembler
* Demonstration of use of timer 0 and the prescaler
* Use of length of instructions to set up timing delays
* Using interrupt routines
* Detection of switch closures including debouncing
* Saving and recovering data from the onboard EEPROM
