Triac regulation using PIC microcontroller
Sometimes there is a need for a regulated AC power source. This can be accomplished with a triac and a microcontroller.
This device uses PIC16C54 microcontroller to control a triac. One push-button has the UP (increase) function, the second one has the DOWN (decrease) function and the third one is for ON-OFF. The ON button will increase the number seen on 7-segment LED display from 00 to 99 which represents triac firing in percentages. Triac can power universal load such as light bulbs, motors and similar.
