Security Door Lock System Using Pic Microcontroller

Now lets see how the system is designed to work as a locker.

Security door lock system using pic microcontroller.

The major components include a keypad lcd and the controller pic16f877a. This article describes the making of an electronic code lock using the 16f877a microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. This project is developed using 8051 microcontroller.

Let us know how to develop this system step by step. So you can use microcontroller based electronic lock to make any device password protected. 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.

The user can also set his password to ensure better protection. In this project we are going to develop a pir sensor and gsm based home security system. If you are not familiar with it then i suggest you to go through this interfacing lcd and keypad with pic microcontroller. 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.
