1) First, we checked if our buzzer was working. We did this by connecting the both wires from the buzzer to the sides of the battery.
2) Then we made a security alarm on the box. We placed our buzzer in the box, and made a small hole in the back, and pushed the right side wire of the buzzer through it. Then we fold a small piece of foil to the box.(over the red wire) Then we make a small hole in the foil and bring the red wire out.
