  digitalWrite(ledPin, HIGH);  // Turn the LED on
  delay(1000);              // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);              // Wait for 1 second

void loop() {
  int sensorValue = analogRead(potPin);  // Read the analog value from the potentiometer
  Serial.print("Sensor value: ");
  Serial.println(sensorValue);  // Print the sensor value to the serial monitor
  delay(100);  // Wait for 100 milliseconds before taking the next reading
}

  Wire.beginTransmission(SLAVE_ADDRESS);  // Start transmission to the I2C slave device
  Wire.write(0x01);  // Send data byte (e.g., command or data)
  Wire.endTransmission();  // End transmission
