 * TimeRTC.pde
 * Example code illustrating Time library with Real Time Clock.
 * This example is identical to the example provided with the Time Library,
 * only the #include statement has been changed to include the MCP79412RTC library.
#include <Time.h>  
#include <Wire.h>  
#include <MCP79412RTC.h>  //http://github.com/JChristensen/MCP79412RTC
void setup()  {
  Serial.begin(9600);
  setSyncProvider(RTC.get);   // the function to get the time from the RTC
  if(timeStatus()!= timeSet) 
     Serial.println("Unable to sync with the RTC");
     Serial.println("RTC has set the system time");      
void loop()
   digitalClockDisplay();  
   delay(1000);
void digitalClockDisplay(){
  // digital clock display of the time
  Serial.print(hour());
  printDigits(minute());
  printDigits(second());
  Serial.print(" ");
  Serial.print(day());
  Serial.print(" ");
  Serial.print(month());
  Serial.print(" ");
  Serial.print(year()); 
  Serial.println(); 
void printDigits(int digits){
  // utility function for digital clock display: prints preceding colon and leading 0
  Serial.print(":");
  if(digits < 10)
    Serial.print('0');
  Serial.print(digits);
