Our group decide to do a keypad, a LED, a buzzer and a siren, we wrote the keypad code, but we don’t have any idea about the LED code, because we want to do that when the siren starts to sound, the LED will start from on to off, to indicate that someone is trying to stole our card, or we press any key to display the alarm, the LED have to start to run… how can we do that?
