Here is the circuit diagram of a compact RTC module, based on the popular RTC IC DS1307, for your everyday microcontroller projects. The DS1307 serial real-time clock (RTC) is a lowpower, full ...

Developers, makers and hobbyists looking for a real time clock module complete with an Arduino library, may be interested in the Kraztech Real Time Clock Module created by developer Christopher ...

The RTC module is crucial for keeping accurate time, even when the Arduino is powered off. It maintains the time using a small battery, ensuring that the clock remains accurate.

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

He’s made a real-time-clock module controlled by a rubidium frequency standard, and since it also includes a GPS clock he can track local time dilation effects by comparing the two.

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.
