Smart library access

This project is about smart Library access where the student or staff use code or password to access the library that have been given password, this is because to prevent from outsider enter the library without permission and to prevent many unwanted event from outsider.This project need to key in the password required to enter the library, if the person enter wrong password the display will show warning and the buzzer beeping and need to reenter the the true password.This access is a device built around PIC 16F877A which act as interface between hardware and software.This access actives an output when correct access cade has been entered on keypad.This code consist of six digit in the range 0 to 9.The code can be changed by user and is also remembered when the power is off.The main objective of this project is to product low cost and user friendly electronic device. This project were control by using PIC16F877A and need to burn a coding that were made into the PIC, the coding were made by using the software name MPLAB X IDE vl.85. The design prototype has been fabricated and the output was shown in the software name Proteus 8 Professional. Therefore, through this proposed techniques, it is expected that not only will efficiently smart access but as hight technology security.
