Security Door Lock System Using Pic Microcontroller

Let us know how to develop this system step by step.

Security door lock system using pic microcontroller.

The major components include a keypad lcd and the controller pic16f877a. The password is entered by making use of a keypad. This project is developed using 8051 microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones.

This article describes the making of an electronic code lock using the 16f877a microcontroller. For example speed control of a dc motor home automation system automatic doors and measurements systems can be made password protected the electronic bell of school can also be made password protected using the electronic lock. This system allows the user to unlock the device with a password. Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.

If you are not familiar with it then i suggest you to go through this interfacing lcd and keypad with pic microcontroller. So you can use microcontroller based electronic lock to make any device password protected. Key this key is meant to initialize the system when the system is turned on the controller will scan only this key and pressing this key will enable. The user can also set his password to ensure better protection.
