PIC based Countdown Timer
The purpose of this timer is to provide a countdown time from 1 second to 99 minutes & 59 seconds. It used to control the lighting for the Ultra-Violet exposure of photosensitive PCB material. The project provides also an audible alarm at the end of the countdown time and switches the UV lights by means of a relay. It is based on a Microchip microcontroller, the 18 pin PIC16F84(A). There are 15 different modes to program countdown times.
