Triac Regulation using PIC microcontroller

This device uses PIC16C54 to control a triac. One push-button has the UP (increase) function, second one has the DOWN function and the third one is for ON-OFF. Button ON will increase the number on LED display from 00 to 99 which represents triac firing in percentages. Triac can power universal load such as light [...]

LED Clock 12/24hrs

This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it “The ANP LED Clock”. (ANP stands for Almost No Parts.) Using the micro controller PIC 16F84A or the 16F628 (same pinout), this clock have more and [...]
