{
Serial.println(“Authorized access”);
Serial.println();
delay(500);
digitalWrite(LED_G, HIGH);
tone(BUZZER, 199999);
delay(300);
noTone(BUZZER);
myServo.write(180);
delay(5000);
myServo.write(0);
digitalWrite(LED_G, LOW);

}

else {
Serial.println(" Access denied");
digitalWrite(LED_R, HIGH);
tone(BUZZER, 5);
delay(1000);
digitalWrite(LED_R, LOW);
noTone(BUZZER);
