1. Connect LED anode to Relay dengan digital pin (pin 13)
2. Connect LED catode to resiston (200-ohm) and the to the ground (GND) of the Arduino board.
3. Connect one leg of the push button to the digital pin (pin 2).
4. Connect the other leg of the push button to the ground (GND) of the Arduino board.
