This repository contains a complete and well-documented digital clock built using an Arduino Uno or Arduino Nano, a DS3231 high-accuracy real-time clock (RTC) module, and a 16×2 I2C LCD display. The ...

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 ...

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 ...

A new Arduino-powered voice-activated clock has been created by Instructables user GeraldF6, who has kindly published step-by-step instructions enabling you to build your very own. This innovative ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

The RV-3028-C7 is an extremely precise, extremely low power, highly configurable RTC. Under ideal conditions it runs at approximately 40nA with +/-5ppm per year of deviation (+/- 160 seconds worst ...
