/****** SYSTEM REQUIREMENTS *****/
/****** SYSTEM REQUIREMENT 1 *****/
/* Il programma inizia visualizzando una barra di */
/* caricamento sull'LCD. Successivamente deve partire */
/* un timer di 10 minuti e sull'LCD dev'essere */
/* visualizzato "INSERIRE PASSWORD" e nel frattempo */
/* dev'essere riprodotta la "traccia1.mp3" dal */
/* DFPlayerMini. */
/****** SYSTEM REQUIREMENT 2 *****/
/* Attraverso il keypad dev'essere monitorata */
/* l'introduzione di un codice composto da 4 numeri e */
/* finalizzato con carattere #. */
/****** SYSTEM REQUIREMENT 3 *****/
/* Se i 4 numeri sono uguali alla password "5421" */
/* allora deve accendersi il led verde e sull'LCD */
/* deve comparire la scritta "CODICE CORRETTO, BOMBA */
/* DISINNESCATA". Se sbagliato "CODICE SBAGLIATO, */
/* RIPROVA". */
/****** SYSTEM REQUIREMENT 4 *****/
/* Durante il countdown deve lampeggiare il led BLU. */
/* Se il countdown raggiunge 10 secondi allora la */
/* traccia audio "traccia2.mp3" e "traccia3.mp3" */
/* devono essere riprodotte. */
/****** SYSTEM REQUIREMENT 5 *****/
/* Se il countdown termina e non viene inserita la */
/* password giusta allora il led rosso deve */
/* accendersi ad intermittenza e devono essere */
/* riprodotte le tracce mp3 "traccia4.mp3", */
/* "traccia5.mp3" e "traccia6.mp3". */

/********* User code review feedback **********
#### Feedback 1 ####
- il countdown deve partire subito all'avvio e non essere dipenden
