char pass[] = "Your_WiFi_Password";

BlynkTimer timer;

void setup() {
  // Initialize Blynk and Wi-Fi
  Blynk.begin(auth, ssid, pass);
  
  // Connect the siren to a digital pin on the ESP32 board
  pinMode(21, OUTPUT);
}

void loop() {

  timer.run();
  
  // Define a Blynk virtual pin for the alarm trigger
  BLYNK_WRITE(V0) {
    if (param.asInt() == 1) {
      // Sound the siren when the alarm is triggered
      digitalWrite(21, HIGH);
      delay(5000);
      digitalWrite(21, LOW);
    }
  }
}

# Set up the GPIO pin as an output
GPIO.setup(siren_pin, GPIO.OUT)

def sound_siren():
    # Turn on the siren for 5 seconds
    GPIO.output(siren_pin, GPIO.HIGH)
    time.sleep(5)
    # Turn off the siren
    GPIO.output(siren_pin, GPIO.LOW)

# Call the sound_siren function when needed
