CRANE GAME

Step 30 Wire the joystick

                                                      
The wiring got a bit messy. 

Basically every pushbutton is connected to a 10K pull-down resistor on one side and 5V on the other.   The arduino pin for each button will be connected between the button and the resistor.

So each button goes like this:

Button  (one side)---> Arduino input pin  --> 10K resistor  -->ground on arduino
Button  (other side)---> 5V on Arduino

Now when a button is open, the output to arduino will be low.  When the button is pushed it will be high.

I used Cat-5 network cable for this.

Here is the wiring to the buttons on the controller and to the Arduino -

Wire - Button - Arduino Analog/Digital:

Blue - Up (joystick) - A0 / D14
Blue/white - Down (joystick) - A1 / D15
Orange - Left (joystick) - A2 / D16
Orange/white - Right (joystick) - A3 / D17
Green - Left button (claw open) - A4 / D18
Green/White - Right button (claw close) -A5 / D19
Brown - Ground (Arduino) - Ground
Brown/White - 5V (Arduino) - 5V

(note: the analog pins on the Arduino can be used as digital pins)
