To use this library, first, we need to install this library in Arduino IDE by going to Arduino’s library manager. Therefore, to program a DS3231 RTC module with Arduino, you will use the RTClib library available in Arduino IDE. We can use simple callback functions implemented by RTClib to read data from DS3231. This library hides all the complexity to communicate with an RTC module over I2C communication. Fortunately, an Arduino RTClib library is available which provides callback functions to take time measurements from an RTC module. If you don’t know about I2C communication, you can check these articles:īut it requires an effort to write a code from scratch. To program a DS3231 RTC module, we need to use I2C communication pins of Arduino. Arduino UNO RTC Module 5V VCC GND GND ICSP2 Header SDA ICSP2 Header SCL Install DS3231 RTC Library in Arduino IDE The schematic of the module is provided to understand the connections which may turn helpful while repairing the module:Īs explained earlier, we will interface an Arduino UNO with RTC as an example:Ĭonnect the pins accordingly.
