Leete esta PAGINA y sabras que hacer con el trozo de codigo:

 lcd.setCursor(0, 0);
  lcd.println(F(" Bienvenido "));
  digitalWrite(Buzzer, HIGH);
  delay(500);
  digitalWrite(Buzzer, LOW);
  digitalWrite(RELAY, LOW);
  delay(250);
  digitalWrite(RELAY, HIGH);
  lcd.clear();

que tanto repites. No creo que se pueda simplificar mucho mas.

No puedo probarlo pero si funciona creo que esta mas simple no?

Si es mucho mas simple pero me lanza el error (decomposition declaration cannot be declared with type 'String')

Ya funciona con un cambio que hice pero al poner todos los tags la memoria dinamica se pasa al 150%

Bueno, habra que ponerlo en PROGMEM o sea en la flash.
Me ha costado porque no se pueden guardar los String en PROGMEM o sea en las Flash.
Asi que he hecho esto mirando por acá y por allá.
Funciona porque lo probé a nivel del almacenamiento nada mas.
