Prototipe Pengaman Pintu Menggunakan Kunci Digital Berbasis Pengendali Mikro ATMega8535

Abstract

A door system using password can be a security system which is used to protect valuable products from outsiders. In this case, a door protected with password is used to protect facilities or valuable documents in a room. This research is conducted by developing a prototype of door system which is equipped with alarm as an indicator if there are some mistakes in entering the password three times in a row; LCD as a displayer; keypad as a media to enter the password; and microcontroller ATMega8535 as a controller. The final result is a doors security prototype using password in which door can only be opened if the password is correct. On the the contrary wrong password inserted in, the door can not be opened.
