Thanks sir for reply :slight_smile:

I used loop at end bcoz i want to run code once only not in loop. I updated my circuit as per img ref below

Updated code

#include <LiquidCrystal.h>

const int buttonPin = 7;
int buttonState = 0;

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

lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("Hello All");

// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);

if (buttonState == HIGH)

// Print a message to the LCD.
lcd.print("Jon");

}

void loop()
{

}

but still its not working only showing "Hello All "
