The code on the Arduino:
Code: Select all
// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
#include <Wire.h>
#include "RTClib.h"

void setup () {

if (! rtc.begin()) {
Serial.println("Couldn't find RTC");
while (1);
}
if (! rtc.isrunning()) {
Serial.println("RTC is NOT running!");
rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
DateTime now = rtc.now();
rtc.adjust(DateTime(now.year(), now.month(), now.day(), now.hour(), now.minute(), now.second() + 6));
// It takes about 6 seconds from compilation to when the time is actually set - check this, it varies
}
}
