Read the first part!


Write up coming soon!

The schematic is created using Fritzing. Download Fritzing and open this file to view the circuit.






Codes

// Global area
#include "LCD4884.h"
// Add library & related includes file here
#include <WProgram.h>
#include <Wire.h>
#include <DS1307.h>

const float MULTIPLIER = 0.48828;

// Initialization that run on
// powerup or after reset
void setup(){
 
  // Add code to initialize the RTC lib here
  RTC.stop();
  RTC.set(DS1307_SEC,1);  //set the seconds

  RTC.set(DS1307_YR,9);   //set the year
  RTC.start();
