How to display time on 16x2 LCD

Using Arduino Displays
3

Don't know if this helps, but it uses an RTC (DS1307 or similar), Uno and a 16x2 LCD display.

#include <Wire.h>
#include "RTClib.h"
#include <LiquidCrystal.h>
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
//LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
RTC_DS1307 RTC;

void setup () {
Serial.begin(9600);
Wire.begin();
RTC.begin();
lcd.begin(16, 2);

// pinMode(8,OUTPUT);

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(DATE, TIME)); // Use ONCE then comment out and reload
//RTC.adjust(DateTime(2014,10,25,21,10,0)); // Set time manually ONCE as above
}
}

void loop () {
DateTime now = RTC.now();
lcd.setCursor(0, 0);
//lcd.print("Digital Clock");
lcd.setCursor(0, 0);
lcd.print(now.day(), DEC);
lcd.print('/');
lcd.print(now.month(), DEC);
lcd.print('/');
lcd.print(now.year(), DEC);
lcd.print(' ');
lcd.setCursor(0, 2);
if (now.hour()<10)
lcd.print('0');
lcd.print(now.hour(), DEC);
lcd.print(':');
if (now.minute()<10)
lcd.print('0');
lcd.print(now.minute(), DEC);
lcd.print(':');
if (now.second()<10)
lcd.print('0');
lcd.print(now.second(), DEC);
lcd.setCursor(12, 0);
int dayofweek = now.dayOfWeek();
switch(dayofweek){
case 1:
lcd.print("Mon");
break;
case 2:
lcd.print("Tue");
break;
case 3:
lcd.print("Wed");
break;
case 4:
lcd.print("Thu");
break;
case 5:
lcd.print("Fri");
break;
case 6:
lcd.print("Sat");
break;
case 0:
lcd.print("Sun");
break;
delay(1000);
}

}
