28 led clock timer

This is a programmable clock timer circuit that utilizes individual LEDs to signify hours and minutes. Twelve LEDs can be arranged in a circular formation to represent the 12 hours of a clock face, while an additional 12 LEDs can be positioned in an outer circle to indicate 5-minute intervals within each hour. Four additional LEDs are employed to represent 1 to 4 minutes of time within each 5-minute interval.

The programmable clock timer circuit is designed to provide a visual representation of time through the use of light-emitting diodes (LEDs). The arrangement of 12 LEDs in the inner circle corresponds to the traditional clock face, allowing users to easily identify the hour. Each LED in this circle is illuminated sequentially based on the current hour, providing a clear and intuitive display.

Surrounding the inner circle, the additional 12 LEDs serve to indicate 5-minute increments. Each LED in this outer circle is activated to represent the passage of 5 minutes, effectively dividing the hour into manageable segments. This feature enhances the circuit’s usability, allowing for quick assessments of time intervals.

To further refine the time display, four more LEDs are integrated into the design to indicate the specific minutes within each 5-minute interval. These LEDs illuminate in a sequential manner, providing a detailed breakdown of time that can be particularly useful for countdown applications or timed events.

The circuit can be programmed to set specific times or intervals, allowing for versatility in various applications. The use of microcontrollers or timers in conjunction with the LED arrangement enables the programmable features, making it suitable for both educational purposes and practical applications in timing tasks.

Power supply requirements for this circuit typically involve a low-voltage DC source, ensuring that the LEDs operate efficiently without excessive power consumption. Resistors are also included in the design to limit current flowing through the LEDs, preventing damage and prolonging their lifespan.

Overall, this programmable clock timer circuit exemplifies an innovative approach to timekeeping, combining visual elements with functional programming to create a user-friendly and efficient timing solution.This is a programmable clock timer circuit that uses individual LEDs to indicate hours and minutes. 12 LEDs can be arranged in a circle to represent the 12 hours of a clock face and an additional 12 LEDs can be arranged in an outer circle to indicate 5 minute intervals within the hour. 4 additional LEDs are used to indicate 1 to 4 minutes of time within each 5 minute interval.. 🔗 External reference
