Write program to show clock on LCD as follows for Arduino.

 


Here i am using online IDE Tinkercad . If you don't know what is tinkercad then refer my blog HERE or else you can use offline IDE also.

Code :- 

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); 

void setup() {

  lcd.begin(16, 2);

}

void loop()

{

for(int h=0;h<24;h++)

  {

lcd.setCursor(5,0);

lcd.print("TIME");

lcd.setCursor(3,1);

if(h<10)

lcd.print("0");

lcd.print(h);

lcd.print(":");

for(int m=0;m<60;m++)

    {

lcd.setCursor(6,1);

if(m<10)

lcd.print("0");

lcd.print(m);

lcd.print(":");

for(int s=0;s<60;s++)

      {

lcd.setCursor(9,1);

if(s<10)

lcd.print("0");

lcd.print(s);

delay(1000);

      }

    }

  }

}

Output :-
