Programming Power Fail Logger with Arduino IDE

To Set the RTC Using the Arduino IDE copy the follow program and paste in the Arduino IDE.

This code can be found here:https://github.com/rodan/ds3231

 #include <Wire.h>
 #include <ds3231.h>
 struct ts t; 
 void setup() {
 Serial.begin(9600);
 Wire.begin();
 DS3231_init(DS3231_CONTROL_INTCN);
 /*----------------------------------------------------------------------------
 In order to synchronise your clock module, insert timetable values below !
 ----------------------------------------------------------------------------*/
 t.hour=20; 
 t.min=40;
 t.sec=0;
 t.mday=11;
 t.mon=4;
 t.year=2021;
 DS3231_set(t); //Comment out after setting RTC with time & date
 }

 void loop() {
 DS3231_get(&t);
 Serial.print("Date : ");
 Serial.print(t.mon);
 Serial.print("/");
 Serial.print(t.mday);
 Serial.print("/");
 Serial.print(t.year);
 Serial.print("\t Hour : ");
 Serial.print(t.hour);
 Serial.print(":");
 Serial.println(t.min);
 Serial.print(":");
 Serial.println(t.sec);
 delay(60000);
 }
 void print2digits(int number){
 if (number >= 0 && number < 10) {
   Serial.write ('0');
 }
 Serial.print(number);
 } 

Connect the Power Fail Logger to the Arduino uno.
