#include <Wire.h>

#include "RTClib.h"


RTC_DS1307 rtc;


char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

  Serial.begin(57600);

  if (! rtc.begin()) {

    Serial.println("Couldn't find RTC");

    while (1);

  }


  if (! rtc.isrunning()) {

    Serial.println("RTC is NOT running!");

    // following line sets the RTC to the date & time this sketch was compiled

    rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));

    // This line sets the RTC with an explicit date & time, for example to set

    // January 21, 2014 at 3am you would call:

    // rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));

  }

   rtc.adjust(DateTime(2019, 6, 17, 15, 22, 0));

}


void loop () {

    DateTime now = rtc.now();

    

    Serial.print(now.year(), DEC);

    Serial.print('/');

    Serial.print(now.month(), DEC);

    Serial.print('/');

    Serial.print(now.day(), DEC);

    Serial.print(" (");

    Serial.print(daysOfTheWeek[now.dayOfTheWeek()]);

    Serial.print(") ");

    Serial.print(now.hour(), DEC);
