It also provides an overview of the current and future market situation.

Keypad module

A keypad module is a component that can control the password door lock. The idea is to provide a lock that can be released only with a password entered by the actual user. The password is typically predefined. Upon entering the correct password, the lock will release. It will display a visual indication of the unlock status. It also comes with an LCD display to guide the user through the password entry process. This module can also be programmed to change the default password.

This device is also known as a password-based circuit breaker, or a fingerprint sensor. It works the same way, and contains three devices: a keypad, a microcontroller, and a password-encoder. The keypad is used to input the password. The keypad is a 4-by-four matrix with four rows and four columns. After entering the password, the microcontroller will reset the state of the relay switch. When the password is entered correctly, the lock will close automatically.

When the user presses a button, the microcontroller will detect it and execute a function. It will display the keynum in a 4-digit display and then check whether the user has entered a password. If the input is valid, the servo will move 180 degrees to the unlocked position and the door will remain open for ten seconds. The variable openSeconds can be adjusted in setup().

To use a keypad with an Arduino, connect the four-by-four keypad to pins A0 to A5 on the board. The keypad’s pins correspond to the digital pins 3 and 2. You can also use the V0 pin to control the contrast of the LCD. After you input the password, the system will compare the password with the stored password of 1234. The four-by-four digits are then stored in a variable called mypassword.

DC motor

A DC motor for password door lock is a smart and secure option for locking doors. This door lock is controlled by a microcontroller, AT89S52, which accepts the password from a keypad and compares it to a predefined password stored on the lock. This keypad-based door lock has a LCD display, which is used to give the user instructions. Once a password is entered, the lock will open or close the door.

The microcontroller sends commands to the LCD screen. When the LCD screen shows “enter password,” the user enters the password on the keypad. The controller compares the entered password to a pre-programmed password, P0.0 and P0.1 are made HIGH and LOW respectively. The microcontroller then receives input signals from the controller and drives the DC motor to move forward. This process continues until the door is closed.

The password-based door lock features an 8051-mini operator to make the digital code hair. This processor handles the load with the help of mathematical passwords. If the input key matches the Data Master, the door will open. Otherwise, the door will remain locked until the user pulls the lock needle. A video link is provided so that the user can see the complete working of the door lock. The video below demonstrates this process in more detail.

The microcontroller is the heart of the system. It provides control to the load. The microcontroller reads the password from a keyboard, displays the status, and controls the motor. The motor will rotate depending on the authenticity of the password. The door will be unlocked after the person has entered the correct password. However, if the password is incorrect, the lock will close. Therefore, it is important to have the correct password.

LCD display

To build an LCD display for a password door lock, you’ll need an Arduino UNO board and an LCD. The LCD will display the password message and the servo motor will push or pull the latch to open the door. To display the message, you’ll need a 16×2 LCD (two rows and sixteen columns). Learn more about LCD Display Modules for Arduino in the following tutorial. Here’s a more detailed walkthrough:

A 16*2 LCD and a 4×4 matrix keypad are the main components of the system. The keypad is an input interface. When a user enters the correct password, the door locks and displays a message on the LCD. The output pin is made high. The door lock system can be used for a variety of applications, from homes to banks. The user can even change the password at any time.

The LCD display for a password door lock works in a simple way. Entering the password is as easy as pressing a single key. The LCD displays the four-digit passkey. When the passkey matches the preset password, the lock output pin goes high. If it matches, the lock unlocks. If the user enters the wrong password a third time, the lock automatically locks. It can be programmed to lock the door after three incorrect attempts.

The microcontroller at89C51 has two input ports. The P2 pin connects to data pins seven to fourteen. The P10 and P11 pins are connected to the control pins EN and RS of the LCD. Port P0 is used for keyboard input and port P07 is used to connect to the lock output pin. It’s important to keep these pins in the correct order so that the lock will work properly.


The Processor for Password Door Lock provides a secure, reliable and intelligent way to unlock the door with the use of a fingerprint or a code. The processor works by generating a new password immediately on user authentication, which is done by scanning fingerprints. It is also capable of determining whether the person is a determined user and thus improves the door locking system’s security. Here are a few of its main features:

The PIC microcontroller is responsible for controlling the LCD display and keypad. The microcontroller is responsible for maintaining the low levels of P2.2 and P2.3. When the user attempts to open the door by entering the wrong password, the LCD screen displays a failed message. The LCD also keeps the door closed until the user changes the password. Once the user has changed the password, the system goes back to the initial state of receiving a password and opening the door.

The 8051 microcontroller is the heart of this electronic code lock system. It receives input from a keyboard and actuates a load. In the Password Based Door Lock System, the microcontroller determines if a person is qualified to enter the password. Then, if the person has entered the correct password, the door will open, and if they have not entered a password, the door will be closed.

The processor for Password Door Lock comprises two main components: the keypad module and the motor driver. The keypad acts as the input interface and controls the dc motor. The processor also controls the LCD display and provides the user with the status messages. These two components are integrated into a single device, so they are highly efficient. Moreover, they have the advantage of being energy-efficient and low-power consumption. It is also suitable for high-end buildings and public places.
