Concept: The project aims to create a digital clock that displays the current time and date using a DS-3231 real-time clock (RTC) module and a 4-digit 7-segment display. The clock can be set manually, and the time and date will be updated automatically.

Working Method:

1.            The DS-3231 RTC module is connected to the Arduino board, along with the 4-digit 7-segment display.

2.            The Arduino board is programmed to read the time and date from the RTC module and display it on the 4-digit display.

3.            The clock can be set manually using buttons connected to the Arduino board. The user can set the hours, minutes, and date by adjusting the buttons.

4.            The Arduino board will update the time and date automatically based on the information received from the RTC module.

5.            The clock will continue to display the time and date until the Arduino board is reset or powered off.
