Time based changing password
In Electronics Access control system , we will control the door using password protection. In thisd project we will control it using microcontroller 89C051. we will use key matrix to enter data, if entered data will match with stored data in microcontrolller, then only it will allow the door to open , otherwise it will remain locked.
The main key in this project is coding of password.we will use DC motor to open the door , so that door will open step by step.
We will use LCD display to show the entered password.
It will also show the entered password match with stored password, if the password will match then it will show access successful, otherwise it will show denied..
We will use Microswitches to give input to microcontroller.
In keyboard programming we will use linear or matrix keyboard interfacing.
