Standalone door access system (security base)

Abstract

These days the security system is an important part for a house or premise to avoid such incident like robbery. A lot of security systems types have been apply to make sure the safety of the premise. One of them is automatic identification system which really helpful human especially to identify the user passwords (identification) of the premise. Standalone Door Access System (SDA System) is a component that suitable for this project. This project was designed and built using passwords for access the doors of the premise by indentify user. It then output their description such as access status and door number to an attaches LCD screen. The system is powered by using AC to DC adapter. The main idea in this project is to create a system which that can provide security for the safety of the premise. The heart of this project is a PIC 16F628A microcontroller which is used as a brain of the system. It used to control the system through a source code (C code) build using PIC C Compiler software. In this project, passwords are used as an identifier of the user. Additionally, the PIC will process the data which receive from keypad and responsible for sending the output to the LCD screen which shows the character.
