Simple digital voltmeter can be built by using PIC microcontroller and a few discrete components. PIC16F877A 10 bit ADC module was used for this purpose, we’ll work only with 8 upper bits to translate input voltage to digital form and send it to LED display. Hardware of this design is very similar to digital clock … Read more

PIC16F877A Digital Clock

This is PIC16F877A microcontroller based digital clock with 7-Segment display. For this project LTC3710HR was used, however the schematic can be easily adjusted to incorporate larger displays.LTC3710HR is 0.3 inch quadruple digit multiplex common cathode display.Main consideration for choosing the display should be current required as PIC outputs can provide about 25mA for each segment.
