4. Coding

// Coding by Tann Thona (03/12/2020)

#include <LiquidCrystal.h>

const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.setCursor(1,0);
  lcd.print("Welcome 2021");

  lcd.setCursor(2,1);
  lcd.print("TANN THONA");
}

void loop() {
  // Turn off the display:

}
