Attach the following code to the Arduino on your computer.

#include LiquidCrystal

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

void setup() {

Serial.begin(9600);

lcd.begin(16,2);

pinMode(8,INPUT);

}

void loop() {

int a = digitalRead(8);

Serial.println(a);

if(a==1)

{

lcd.setCursor(0,0);

lcd.print("Did you forget");

lcd.setCursor(0,1);

lcd.print("anything?");

delay(2000);

lcd.clear();

}
