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.4.0, cu 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:

    The password is not saved after resetting the Arduino. How do I achieve that stayed?

      I don't know why... for me is an old project, so I must remade the circuit and test againt to see if work or not, but nor very quickly because I'm vee busy... (you have EEPROM library ?)... so, if you change password, it work with new password, but if you power down the Arduino and power up work just old password ?
