/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
	/* Quando il Pulsante1 (PIN D2) è premuto, attiva */
	/* Relay1 (PIN D4) per 10 secondi, poi attiva Relay2 */
	/* (PIN D5) per 20 secondi. Alla fine, entrambi i */
	/* relay devono essere disattivati. */
/****** SYSTEM REQUIREMENT 2 *****/
	/* Attivare Relay3 (PIN D6) quando il Pulsante2 (PIN */
	/* D3) è premuto e disattivarlo quando non è premuto. */
	/* Implementare la logica utilizzando le librerie */
	/* EasyButton e Relay per garantire una risposta */
	/* rapida e affidabile. */
