PASSWORD BASED DOOR LOCKING SYSTEM CIRCUIT OPERATION:

Once the circuit is powered, microcontroller sends commands to the LCD to display enter password on LCD. Now we need to enter the password using the keypad. Once password is entered, it displays 5 stars on LCD to indicate that controller read password successfully.

Now the controller compares the entered password with predefined password. If the password is matched then controller makes P3.0 high. So the base of the transistor gets sufficient current to drive the relay, as a result Door motor rotates to open the door. If the password is not matched then microcontroller makes P3.0 low. Hence door motor is at stationary so that door remains close.

Note: while giving the connections, make sure that there is no common connection between AC and DC supplies.

Password Based Door Lock System Algorithm:

Initially declare the PORT1 to LCD data pins and control pins to P3.5, P3.6 and P3.7 and declare PORT2 to keypad. And use P3.0 to Door motor.
Initially display enter password on LCD.
Now read the five digit password from the user, while reading each digit from the keypad display * symbol on LCD.
Compare the entered password with stored password.
If password is correct then make P3.0 pin high for some time to open the door. After that display Door is opened on LCD.
If the password is wrong then display pwd is wrong on LCD.
After some delay again ask to enter password.
Advantages of Password Based Door Lock System:

This project provides security
Power consumption is less
Used commonly available components
Project is simple and easy
Applications of Password Based Door Lock System Circuit:

This simple circuit can be used at residential places to ensure better safety.
It can be used at organizations to ensure authorized access to highly secured places.
With a slight modification this Project can be used to control the switching of loads through password.
Limitations of Password Based Door Lock System:

It is a low range circuit, i.e. it is not possible to operate the circuit remotely.
If you forget the password it is not possible to open the door.
