SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup() {
  // Initialize Serial Monitor
  Serial.begin(9600);

  // Initialize Bluetooth communication
  bluetooth.begin(9600);

  // Setup potentiometer pin
  pinMode(potentiometerPin, INPUT);
}

void loop() {
  // Read potentiometer value (0-1023)
  int potentiometerValue = analogRead(potentiometerPin);

  // Send potentiometer value over Bluetooth
  bluetooth.println(potentiometerValue);

  // Print potentiometer value to Serial Monitor for debugging
  Serial.println(potentiometerValue);

  // Delay for stability
  delay(500);
}
