Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system. These techniques are an integration of mechanical and electronic devices and highly intelligent. One of the prominent features of these innovative lock systems is their simplicity and high efficiency.

Such an automatic lock system consists of electronic control assembly which controls the output load through a password. This output load can be a motor or a lamp or any other mechanical/electrical load.

DONE AT K A INSPIRE SOFTWARE SOLUTIONS


PROJECT DESCRIPTION
In my project Wireless Digital Code Lock with a Status Display is used to protect the efficient hacking prevent from brute force etc.
The basic user lock is of 4 Digits and Master lock is of 1 digit so it s not easy for an intruder to break the lock unless you keep the code simple.
The input is taken from a 4x3 Keypa ....etc

MICROCONTROLLER-BASED CODE LOCK



INTRODUCTION

Code locks can be constructed using digital and timer ICs employing pushbuttons or keypads for entering the code for authentication and operation of the code lock. However, such circuits would require a large number of ICs.

On the other hand, a microcontroller-based code lock will require very few peripheral components. With the cost of microcontrollers now dropping to be equivalent cost of approximately four digital ICs, it makes sense ....etc
