 ====== Concept ======
-The board is made by **62 portions** : 20 singles, 20 doubles, 20 triples and 2 bull's eye.\\
+The board is made up of **62 segments** : 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**.\\

 Each plastic leaf output as a **plastic ribbon**, holding the leads of an axis of **the matrix**.\\
-In a **8x8 example**, a plastic ribbon hold the X axis (1 to 8) and another the Y axis (A to H) :\\

-Let say a your triple 20  (T20) has the crossing between the "D" and the "3". **For the Arduino and the computer, every portion has its own crossing**.
+Let say, as an example, you hit a triple 20 (T20 here on the picture). A triple 20 switch has the crossing between the "D" and the "3". **For the Arduino and the computer, every segment has its own crossing**.
-So we will **load the representation of the matrix** (a matrix table) in the Arduino, so each time you will hit a portion of your board, it will **send a specific signal** to the computer depending of the row and the column hit on the matrix.

-It is **recommended** (but no more mandatory) to connect **board's buttons** : so "next player", "backup turn" and "give up" can be done directly from board during games. So we need add a column to the matrix.\\

-On the Arduino UNO micro controller, there are severals connectors : A0, A1 ….1,2,3..etc. With the example of a 8x8 ribbons + 1 column for the buttons (= 8x9), you will get something like the **following example** :

-TODO
+Opening the back of the dart board\\

+Unsolder the two slicks from the motherboard\\

+Once the two slicks are free from the main board \\
+Optional : if you wish to use the main board for buttons, we strongly recommend you remove all the components from main board.\\
+To make space for the Arduino, Cut the main board without cutting the places near the circuit of buttons.\\
+{{:04-unsolider03.png?nolink&500|}}
+Prepare your Arduino and your cables\\
+{{:05-arduino-prepared01.png?nolink&500|}}
+You final assembly could look like the following \\

+Re-attach the back of your board. The hardest part is done !\\
