| Abstract | ||
| This work describes the design and the implementation of a low cost high security electronic lock system based on PIC microcontroller embedded system. The proposed system includes a thirty-eight buttons keypad panel interface, 16x2 LCD and a PIC16F887 microcontroller.This work introduces two main challenges; The first one in physical matching the proposed 38 buttons keypad to the proposed PIC microcontroller, so that each button will represent a specific unique single digit (number or character) without interfering to each other. The second one is in writing the PIC program (firmware) that will handle and recognize each input digit in order to be processed by the internal center processing unit of the microcontroller for performing specific task.The proposed system is implemented using PIC16F887 microcontroller because of it low cost then capsulated as an integrated system and tested under real conditions. The results of the tests shows a highly reliable security lock system with a completely error-free design which makes so practical for security application such as doors, gates, garages and safes. | ||
