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
- We will connect the DS3231 module
- 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
