Step 13Making the Electrical Connections
With your buttons, LEDs, and terminals installed, you are ready to connect these components on the back of the board.
1. Using short lengths of red wire, connect one of the two terminals next to the map labels to each of the buttons, as shown in Figure below. This will be the power terminal.
2. With longer lengths of red wire, connect the open side of each button to the power pin of the appropriate LED, as shown in Figure. (NOTE: Be sure to match buttons to LEDs correctly! You may want to label the buttons and LEDs on the back.)
3. Using two short lengths of black wire and a resistor, connect the two open terminals, as shown in Figure. These will be your ground terminals.
4. With longer lengths of black wire, connect the ground pins of the LEDs to the terminal screw beneath the map labels, as shown in Figure.
5. Connect the red and black battery lead extensions to the board, as shown in Figure.
6. Finally, connect the battery pack to the battery lead extensions, as shown in Figure.
