DUAL AXIS JOYSTICK
 
- analog dual-axis joystick with cap
- power voltage: 3.3 - 5V DC
- dimension: 34 x 26 mm
- height: 32 mm
- two integrated bi-directional 10K resistors
- integrated push-button
- easy to use with Arduino 
 
Arduino code:
 
int Joystick_X = 0;  // x axle
int Joystick_Y = 1;  // y axle
int Joystick_Z = 3;  // push-button
 
void setup () {  
  pinMode(Joystick_X, INPUT);
  pinMode(Joystick_Y,  INPUT);
  pinMode(Joystick_Z,  INPUT);
  Serial.begin(9600);   
}
 
void loop () {  
  int x = analogRead(Joystick_X);  // read x axle
  int y = analogRead(Joystick_Y);  // read y axle
  int z = digitalRead(Joystick_Z);   // read button status 
 
  Serial.print(x, DEC); Serial.print( ",");
  Serial.print(y, DEC); Serial.print( ",");
  Serial.println(z, DEC);
}
