Sample Arduino Code Snippet

Here’s a simple sketch to read joystick values:

int joyX = A0;

int joyY = A1;

int button = 2;

void setup() {

Serial.begin(9600);

pinMode(button, INPUT);

}

void loop() {

int xValue = analogRead(joyX);

int yValue = analogRead(joyY);

int btnValue = digitalRead(button);

Serial.print("X: "); Serial.print(xValue);

Serial.print(" | Y: "); Serial.print(yValue);

Serial.print(" | Button: "); Serial.println(btnValue);

delay(200);

}
