Step 9Put it all together
The basic wiring idea is this:
From the battery, run the positive wire through a resistor, then connect to one side of a reed switch. Connect the other side of the reed switch to the positive connection of the object you are wiring in. From that object, run a negative wire back to the negative side of the battery.
All the wiring follows that same pattern with a few minor variations.
The LED's we have require unique resistors for each color (we can't wire white and blue LED's through the same resistor - only one color will light up at a time if wired that way). I used different color wires for the different LED's. Black wire was used for blue LED's and white wire was used for white LED's.
From a 9V battery, I soldered a wire and resistor for the blue LED's, one for the white LED's, and one for the street lights. The train runs on a different battery.
From the black wire, I connect a wire to each reed switch that is under a Chance spot and the water company spot because those all light up blue LED's. From the white wire, I connect a wire to the reed switches for the community chest spots because the light on the chest is white.
For all three Community Chest reed switches, I connected another wire to the other side of the reed switch. Those wires all come together to connect to the positive side of the white LED wire for the chest. From the negative side of the LED I ran a wire back to the battery. I used the same technique to wire the Chance spots.
In the community chest, I have the dial set so that it moves when you land on the community chest spots. The positive wire from the battery tester is wired in to the positive wire from the LED on the same chest. The negative wire from the battery tester dial is wired into the negative wire from the LED.
To wire in the street lights, it took a bit of wire cutting and hole drilling. I placed the lights on the board where I wanted them and drilled a hole for the wires to go under the board. The streetlights had two wires twisted together and I marked one of the wires with a black sharpie so I would know which wires to reconnect under the board. I cut the wires, passed them through the board, and then reconnected them underneath.
For the streetlights, you want the resistor that was used in the battery pack. Cut it out and add it to the line from the battery to the reed switch at the Electric Company. I know the resistors I have cut the power to about 3 volts. The extra resistor will cut the power down to the appropriate level for the lights.
Now that the streetlights are wired into the board, I can use the battery pack to hold a AAA battery for the train! I made a wire coil to hold the AAA battery in the AA battery pack. It holds the battery in place and makes the connection to the battery contacts. Cut the wires on the back to connect to the train wires underneath the game board.
I glued the ray gun base in place as well as the community chest. I ran all the wires underneath, connected them and checked them.
