Project Overview

The Large 7-Segment Clock Display project aims to create a highly visible and accurate timekeeping solution using a combination of decade counters and 7-segment displays. This large-scale display is designed to be legible from a significant distance, catering to scenarios where visibility is crucial, such as public spaces or outdoor environments.

Key Features:

• Clock Accuracy: The project incorporates a stable clock source to ensure accurate timekeeping. The clock signal is generated to tick precisely once every second, providing a reliable and precise time reference.
• Legibility and Visibility: The 7-segment display is optimized for readability even from a distance of up to 100 meters. This feature is particularly valuable in scenarios where the display needs to be visible across large spaces or outdoor environments.
• Mains Operation: The clock system is designed to operate seamlessly from the mains power supply. This ensures a consistent and reliable power source for continuous operation.
• Time Setting Mechanism: A robust mechanism for setting the time is implemented, allowing users to adjust the displayed time as needed. This feature enhances the versatility of the display, accommodating various use cases and scenarios.
• Every 15-Minute Beep: To provide additional functionality, the clock system includes a periodic beep every 15 minutes. This audible signal serves as a timekeeping notification, adding a layer of user interaction and awareness.
• 12-Hour Clock: As an additional feature, the project offers the option to display time in a 12-hour format. This caters to different timekeeping preferences and adds flexibility to the display's functionality.

Implementation:

The implementation involves the use of decade counters to divide the clock signal and drive the 7-segment displays. The design incorporates a stable clock source, ensures high visibility, and allows for precise time setting. The periodic beep is achieved through additional circuitry, enhancing the user experience and making the display suitable for various applications.
