The DS1302 is a real-time clock (RTC) integrated circuit with a simple serial interface and 31 bytes of battery-backed SRAM. It keeps track of second, minute, hour, day, day of the week, month, and ...

Repository Description: Embedded real-time clock (RTC) system using PIC16F877A, DS1302 RTC, and MAX6952 LED driver. Displays time (hours & minutes) on a 4-digit 5x7 LED matrix. Utilizes SPI ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without some ...
