GND pin of our Arduino. Finally, the SEL, SW, or

BTN for the internal push-button on the joystick

will be connected to digital pin 4. With that, we

have completed all our basic connections.

WRITING A SIMPLE JOYSTICK DATA SKETCH

int joyX;

int joyY;

void setup() {

Serial.begin(9600);

}

void loop() {

joyX = analogRead(A0);

joyY = analogRead(A1);

Serial.print("Joystick X Value: ");

Serial.print(joyX);

Serial.print(" Joystick Y Value: ");

Serial.println(joyY);

delay(10);

}

Once your code has been uploaded onto your

Arduino, open the Serial Monitor to view the

joystick data (Figure

). As you move the

joystick, you should ...
