7 Segment Display Digital Clock Circuit Diagram. The dc supply is about 5 12v. R1 100kohms r2 47kohms r3 100kohms.
The dc supply is about 5 12v. There are two types of seven segment displays such as common anode and common cathode. Nice project and good to see common anode display with arduino.
The clock display uses 6 pieces of 7 segment led with format hh mm ss.
