Schematic 12 Hour Digital Clock Circuit Diagram. As may be witnessed in the given diagram the heart of the circuit is formed by the ic1 lm8560 which is assigned with the following outputs terminals. For 24h it will count from 00 to 23.
For 12h it will count from 00 to 11. Hours block depending on whether it is a 12 or 24h clock will have a divide 24 or divide by 12. It uses four 7 segment displays the software in the microcontroller allows for very accurate timekeeping.
Now let s learn how the proposed digital clock circuit functions.
We will be using only basic cmos ics and pure logic to build the circuit yet this circuit can be easily replicated by beginners in electronics. Will generate a 1 pph pulse per hour signal to the hours block. For 24h it will count from 00 to 23. As may be witnessed in the given diagram the heart of the circuit is formed by the ic1 lm8560 which is assigned with the following outputs terminals.
