In this project, we are going to make an Arduino alarm clock using the DS3231 real time clock module. This module is very cheap and it works through I2C communication, which makes it easy to use with the microcontrollers. We will get the time using this module and will make the buzzer to beep after comparing the current time with the alarm time. This module also tells us the temperature.
