TVZ2019 / Mbed 2 deprecated SUSTAV_KONTROLE_PRISTUPA

Sustav kontrole pristupa prostoru ostvaren je unosom numeričke lozinke s membranske tipkovnice. Ovisno o ispravnosti lozinke servo motor otključava vrata. Omogućeno je i mijenjanje same lozinke kao i prikaz datuma i vremena na LCD-u.

The area access control system is implemented by entering a numeric password from the keyboard. Depending on the password, the servo motor unlocks the door. It is also possible to change the password itself, as well as display the date and time.
