A detailed description of the Password Based Door Locking System:

It mainly consists of following blocks:

1. Microcontroller: This is the CPU (central processing unit) of our project. We are going to use a microcontroller of the 8051 family. The various functions of the microcontroller are like:
I. Reading the digital input from Keypad
II. Sending this data to LCD so that the person operating this project should read the password
III. Sensing the password using the keypad and checking whether it is a correct password or a wrong password and rotating the stepper motor if the password entered is the correct password.

2. LCD: We are going to use a 16×2 alphanumeric Liquid Crystal Display (LCD) which means it can display alphabets along with numbers on 2 lines each containing 16 characters.

3. Keypad: The user will enter the password using the keypad. Various keys of the keypad are as follows,
I. 0 to 9
II. Enter
III. Escape

Applications and Advantages of Password Based Door Locking System:

  1. This project can be used in offices, companies also at home. It will provide keyless entry.
  2. This can be used in Banks for safety locks.
  3. Users don’t have to carry keys along with them.

Future Development:

  1. We can monitor parameters like fire, overheating
  2. A voice feedback system can be added to the system.
  3. We can interface a GSM modem which will send sms if an invalid attempt is made to open the lock

Questions and answers about this project:

Question: Can you provide a Relay at the output? Can you change the output device from the stepper motor to the DC motor?

Answer: Yes, both options are possible. We can provide a DC motor as well as a Relay as an output device.
