Step 6: Putting everything together
Overlay the wire grid on the LED matrix. You may need to reorder the pin numberings in the LED matrix code to get it synchronised with the wire grid sensor. Secure the wire grid in place with fastenings or adhesives of your choice, and stick on a nice playing board.
Add a switch between pin 12 and ground of the Arduino. This switch is to toggle between 2 player mode, and 1 player mode (vs the microcontroller).
