RTC_DS3231-alarm

A project for setting an alarm using the DS3231 module and then reading the time and alarm flag using an Arduino.

  • Reading time is done using the driver from LibDriver https://www.libdriver.com/docs/ds3231/index.html
  • Time is displayed on a 20x4 LCD
  • After alarm is triggered, alarm flag is cleared for the next cycle
  • Communication between Arduino and RTC module DS3231 is done over I2C
