RTC_DS3231-getSetTime

A project for setting and then reading the time using an Arduino nano and a DS3231 RTC.

  • Set and reading time is done using the driver from LibDriver https://www.libdriver.com/docs/ds3231/index.html
  • Time is displayed on a 20x4 LCD
  • Set time is done once initially, after which the macro WRITETIME has to be disabled
  • Communication between Arduino and RTC module DS3231 is done over I2C
