• Mandatory :
  • An old electronic dart board
  • An Arduino UNO
  • Small cables (like the ones in a old Ethernet cable)
• Optional but could be useful :
  • Auto crimp
  • Connectors
  • Proto board

• Soldering iron
• Unsoldering braid
• Small cables (from an old Ethernet cable for instance)

The board is made by 62 portions : 20 singles, 20 doubles, 20 triples and 2 bull's eye.
When you touch a portion, it quickly shuts a switch. So there is 62 switches behind your dart board. One for each part of your board.

Behind your board, there is two plastic leaves one over the other. They hold all the switches. When your dart press on the board's potion, the two leaves touch themselves, and the circuit is shuts. The signal is sent.

Electronically talking, all the switches are represented by a matrix.
Each plastic leaf output as a plastic ribbon, holding the leads of an axis of the matrix.
In a 8×8 example, a plastic ribbon hold the X axis (1 to 8) and another the Y axis (A to H) :

A : first slick (here with 8 pins, it can be different on your board)
B : second slick (here with 8 pins, it can be different on your board)

X : Arduino inputs
Y : other Arduino inputs

c,d,e : optional buttons. Those buttons are used for “Press player”, “Abort game”, and “Backup turn”
