The user can also set his password to ensure better protection.
Security door lock system using pic microcontroller.
In this project we are going to develop a pir sensor and gsm based home security system.
It can be used to detect any intrusion in houses and offices and send the alerts on cell phones.
So you can use microcontroller based electronic lock to make any device password protected.
Now lets see how the system is designed to work as a locker.
The password is entered by making use of a keypad.
Let us know how to develop this system step by step.
Traditional lock systems using mechanical lock and key mechanism are being replaced by new advanced techniques of locking system.
This article describes the making of an electronic code lock using the 16f877a microcontroller.
This project is developed using 8051 microcontroller.
If you are not familiar with it then i suggest you to go through this interfacing lcd and keypad with pic 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.
