Arduino, un servomotor si o tastatura cu 12 butoane

   In prezentul articol o sa prezint un modul de acces cu parola, cu inchidere manuala sau temporizata, in care elementul de executie e un servomotor.
   Acest articol se bazeaza pe informatiile, schemele si programioarele (sketch-urile) din articolele anterioare:
Arduino si o tastatura cu 12 butoane
Arduino si o tastatura cu 12 butoane (II)
Arduino si un servomotor
   In prima faza am conectat tastatura, afisajul si servomotorul:
schema de conectare fiind:
   Am realizat 2 filmulete:
Arduino - door lock with code - ver.4.0cu timp de acces nelimitat, inchidere prin apasarea tastei '#':
- Arduino - door lock with code - ver.4.1, cu timp de acces limitat la 5 secunde:
   Sketch-ul pentru prima versiune este:
