Digital clock project based on the PIC16C54 microcontroller can be designed using the following circuit diagram. This digital clock electronic project based on the PIC16C54 is a simple time-of-day clock incorporating four seven-segment LED displays and three input switches. There is also an additional reset switch that would not normally be incor

porated into the final design. The displays used were common cathode and turned on with transistors to avoid trying to sink too much current into the PIC16C5X. 100 W resistors were used in series with the segments to obtain the desired brightness. Different values may be required if different displays are used.
