#include <LiquidCrystal.h>

// initialize the library by associating any needed LCD interface pin
// with the arduino pin number it is connected to

// put your setup code here, to run once:
void setup() {
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  
  // Welcome the user
  lcd.print("Welcome!");
  // delay 2 seconds
  delay(2000);
  // clear and reset
  lcd.clear();

  //print hello world
  lcd.print("Hello World!");
}

// put your main code here, to run repeatedly:
void loop() {
