The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module. The RTC module is crucial for keeping accurate time, even when the Arduino is powered off.

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 ...

Because the real time clock module is so accurate, there’s no provision for setting the time. [Barzok] says that twice a year he just hooks the Arduino up and reflashes the program with a new ...

You address it as Arduino. Then it beeps and you can speak a command. There’s also a real-time clock module. Setting up the MOVI is simple: recognizer.init(); // Initialize MOVI (waits for it to ...

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 ...
