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

A Brief Description:
This project is written in C language. Its a simple project with efficient hacking prevention from Brute Force etc. The basic user lock is of 5 Digits and Master Lock is of 10 digits so its not easy for an intruder to break the lock unless you keep the code simple.The input is taken from a 4x3 Keypad (please see the schematic for more information) and Display the user input on a 2x16 LCD. A pin is assigned as output for activating and deactivating the lock. For demonstration i have connected an LED to that pin.
