PIC16F84A Alarm Clock

PIC16F84A Alarm Clock

This clock counts seconds, minutes, hours and day of the week. Time is displayed on 4 seven segment LED displays, and is adjustable with three buttons at start time (up, down, enter). You can program the day of the week, hour, minute and duration of the alarms.

The number of alarms are limited by ROM space only. The alarm is on the RA4 open collector output of the PIC, and is repeated on a decimal point of the display. For once, the program is in BASIC (mikroBasic) and this should make a good start for beginners.
