By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.

Of course, there’s nothing unusual about using 7-segment displays, especially in a clock. However, [Edison Science Corner] didn’t buy displays. Instead, he fabricated them from a PCB us… ...

The heart of the clock is the Arduino Uno, a versatile microcontroller known for its ease of use and flexibility. The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module.
