#include <DS3231.h>

// Init the DS3231 using the hardware interface
DS3231 rtc(SDA, SCL);

void setup()
{
// Setup Serial connection
Serial.begin(115200);
// Uncomment the next line if you are using an Arduino Leonardo
//while (!Serial) {}

// Initialize the rtc object
rtc.begin();

// The following lines can be uncommented to set the date and time
//rtc.setDOW(WEDNESDAY); // Set Day-of-Week to SUNDAY
//rtc.setTime(12, 0, 0); // Set the time to 12:00:00 (24hr format)
//rtc.setDate(1, 1, 2014); // Set the date to January 1st, 2014
}

void loop()
{
// Send Day-of-Week
Serial.print(rtc.getDOWStr());
Serial.print(" ");

// Send date
Serial.print(rtc.getDateStr());
Serial.print(" – ");

// Send time
Serial.println(rtc.getTimeStr());

// Wait one second before repeating :slight_smile:
delay (1000);
