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.
Security door lock system using 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.
The user can also set his password to ensure better protection.
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.
The major components include a keypad lcd and the controller pic16f877a.
This system allows the user to unlock the device with a password.
If you are not familiar with it then i suggest you to go through this interfacing lcd and keypad with pic microcontroller.
Password based door lock system using 8051 microcontroller is a simple project where a secure password will act as a door unlocking system.
This project is developed using 8051 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.
The password is entered by making use of a keypad.
