Introduction: Arduino - DS3231 Real Time Clock

About: Maker 101; Beginner and intermediate level Maker projects! You can find projects such as "How to" and "DIY" on programmable boards such as Arduino, ESP8266, ESP32 and Raspberry Pi on this channel. The projects…

In this tutorial we will learn how to use DS3231 Real Time Clock with the Arduino.

Step 1: Required Hardware

Step 2: About the DS3231 Module

The DS3231 is a low-cost, Real Time Clock Module which can maintain hours, minutes and seconds, as well as, day, month and year information.

The module can work on either 3.3 or 5V. The battery input is 3V and a typical CR2032 3V battery can power the module and maintain the information for more than a year.

Step 3: Connection

  1. We will connect the DS3231 module
  2. We will connect the LCD Display

Step 4: DS3231 Library

This library has been made to easily interface and use the DS3231 RTC with an Arduino or chipKit. The library will also work with the DS3232 RTC chip
