const int ledPinLeft = 9; // Connect left LED to digital pin 9
const int ledPinRight = 10; // Connect right LED to digital pin 10

// Map joystick value to LED brightness (0-255)

// Ensure brightness values are within range

// Adjust brightness for left LED

// Adjust brightness for right LED
analogWrite(ledPinRight, brightnessRight);
