Interfacing of Arduino with 16×2 LCD Display

June 30th, 2018 admin

#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 6, A0, A1, A2, A3);

void setup()
{

  lcd.begin(16, 2);

}
void loop()
{ 

  // Print a message to the LCD.
  lcd.print("Welcome...");
  delay(4000);
  lcd.clear();
  lcd.print("Novel Technology");
  delay(4000);

}
