Password Based Lock Control Using 8051 Microcontroller (AT89C51)

Introduction

As time is going on the necessity of security has become more important in our daily life. For that we are going to propose a new idea based project named “Password Based Lock Control Using 8051 Microcontroller (AT89C51)”. In this proposal any person without knowing the predefined unique password can’t enter through the door. For more security reason user can change the password of this device frequently using the predefined password. This idea can be used in highly secured zone , office campus , research centre , locker room in bank .
