Multifunctional fingerprint lock door

• Pentru a deschide usa, utilizatorul va trebui sa puna degetul pe cititorul de amprenta si se va verifica daca amprenta corespunde cu cea din sistem.
• Exista posibilitatea sa schimbe amprenta prin introducerea unei noi amprente. Prea multe incercari esuate de introducere a amprentei va rezulta in pornirea alarmei.
• Exista si o sonerie care poate fi pornita si un senzor care indica daca o persoana se afla in fata usii.

• Cand se apasa butonul de sonerie (si se mentine apasat), buzzerul va canta o melodie (luata din exemplele de la laborator).
• Cand senzorul ultrasonic detecteaza miscare (intr-o zona in care nu ar trebui sa existe miscare) va suna alarma.
• Pentru a deschide usa trebuie mai intai sa apasam pe butonul de deschidere/inchidere, apoi senzorul de amprente va citi imaginea data.
• Daca senzorul de amprente are in sistem amprenta introdusa, usa se va deschide.
• Cand usa este deschisa, alarma este dezactivata.
• Pentru a inchide usa se apasa pe butonul deschidere/inchidere.

Am conectat senzorul fingerprint la pinii care permit comunicarea cu placa Arduino. Servo motorul deschide si inchide usa de carton.
