3. About Digital Clock What Is Digital Clock? A digital clock is a type of clock that displays time digitally 3

4. History Of Digital Clock The first digital pocket watch was the invention of Austrian engineer Josef Pallweber who created his "jump-hour" mechanism in 1883.  The earliest patent for a digital alarm clock was registered by D.E Protzmann and others on October 23, 1956, in the United States. The Hamilton Watch Company introduced the first digital wristwatch that included an LED display in 1970.  4

10. Implementation :- The image shows a circuit diagram for a digital clock. The circuit is designed to display time using seven-segment LED displays.. The circuit uses several integrated circuits (ICs):- including the 7447N BCD-to-seven-segment decoder/driver and the 7490 decade counter. The 7490 ICs are used to count seconds, minutes, and hours, while the 7447N ICs are used to drive the seven-segment displays to show the corresponding digits. The circuit also includes logic gates (74HC32N) and other components to control the counting and display functions. The VCC 5V labels indicate that the circuit is powered by a 5-volt DC power supply. 10

11. Uses Of Digital Clock Digital Clocks are used in different kinds of devices such as cars, radios, televisions, microwave ovens, standard ovens, computers and cell phones. . 11

12. Advantage of Digital Clock Less expensive. Easy to understand time concept. Give time more accurately than analog clock. Easier to read time. . 12

13. Future Plan Set Time setting , off and on system. Set Date system. Set Alarm system. - 13
