Wire Loop Game

Step 12 Making the Electrical Connections

Now comes the tricky part connecting the path wire, the loop wire, the buzzer, and the battery pack, so that when the loop wire touches the path wire, they form a complete circuit that causes the buzzer to sound.

1. With the game board upside down, identify the buzzer's power lead (the red wire) and ground lead (the black wire).

2. Loosen the nut anchoring the loop wire, wrap the buzzer's power lead around this screw, and retighten the nut.

3. Find the screw that is connected to neither the path wire nor the loop wire, wrap the buzzers ground lead around this screw, and retighten the nut, as shown in Figure.

4. Secure the battery's power lead to one of the two screws anchoring the path wire.

5. Secure the battery's ground lead to the screw with the buzzer's ground lead, as shown in Figure.

6. Connect the battery leads to the battery pack, making sure to align the red and black wires.
