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.

An 8-bit micro from the Microchip brand, it features no Arduino bootloader or USB interface, being flashed via a dedicated programmer. This is combined with a DS1302 real-time clock to keep ...

Good clocks are generally those that keep ... divided up by HH and MM segments. The Arduino fetches the time from a DS1302 RTC module and splits the result up into four-digit time.
