You can use this code as the input method for your menu system or game:

void setup()

{

// initialize serial communication at 9600 bits per second:

Serial.begin(9600);

}

#define Neutral 0

#define Press 1

#define Up 2

#define Down 3

#define Right 4

#define Left 5

// Check the joystick position

int CheckJoystick()

{

int joystickState = analogRead(3);

if (joystickState < 50) return Left;

if (joystickState < 150) return Down;

if (joystickState < 250) return Press;

if (joystickState < 500) return Right;

if (joystickState < 650) return Up;

return Neutral;

}

void loop()

{

int joy = CheckJoystick();

switch (joy)

{

case Left:

Serial.println("Left");

break;

case Right:

Serial.println("Right");

break;

case Up:

Serial.println("Up");

break;

case Down:

Serial.println("Down");
