Project No. 03: Creating a Door lock Security System With Passwords Using Key Pad Passwords
1. Introduction:
In today's world, ensuring the security of our homes, offices, and personal spaces is of utmost importance. To address these needs, we present an innovative project: a door lock system with pass verification using a keypad. The aim of this project is to enhance security and provide a reliable access control mechanism for various spaces.
Our project revolves around a robust hardware setup, consisting of an Arduino microcontroller, a keypad, and a servo motor for door control. By leveraging these components, we have designed a user-friendly and secure system that ensures only authorized individuals can gain access.
The user interface is centered around a keypad, enabling users to enter a passcode for verification. Each user is assigned a unique passcode, allowing for individual access control. Additionally, a master code can be implemented for administrative purposes. Visual feedback, such as LEDs or an LCD display, provides real-time indications of the passcode verification status, ensuring a seamless user experience.
Passcode verification is a crucial aspect of our project. The entered passcode is compared with the stored passcodes to determine if it is valid. Secure storage mechanisms, such as in-memory arrays or external EEPROM modules, can be employed to safeguard the passcodes. By implementing robust verification logic, we ensure that only authorized passcodes grant access.
2. Working:
Step1: Initialization:
Upon powering up the system, the Arduino microcontroller initializes the necessary components, including the keypad and servo motor. The system prompts the user to enter a passcode using the keypad.
Step 2: Password Entry:
The user enters the passcode using the keypad. The Arduino reads and stores the entered passcode.
Step 3: Passcode Verification: The Arduino compares the entered passcode with the stored passcodes. If the entered passcode matches any of the stored passcodes, the verification is successful. If the entered passcode does not match any of the stored passcodes, the verification fails.
Step 4: Door Control:
If the password verification is successful:
The Arduino sends a signal to the servo motor to rotate to the unlocked position. The servo motor physically unlocks the door, allowing entry. Visual feedback, such as an LED turning green or an LCD display showing "Access Granted," can be provided. The system remains in the unlocked state until the door is closed
If the password verification is unsuccessful:
The Arduino does not send a signal to the servo motor, keeping it in the locked position. The door remains locked, denying entry. Visual feedback, such as an LED turning red or an LCD display showing "Access Denied," can be provided. The system can implement additional security measures, such as limiting the number of verification attempts or triggering an alarm.
Step 5: Reset and Repeat:
After a successful or failed verification, the system resets to allow for the entry of a new passcode.
The process repeats for subsequent passcode entries.
3. What is Key pad module:
A 4x4 keypad module is an electronic input device commonly used with Arduino microcontrollers. It consists of a grid of 16 buttons arranged in a 4x4 matrix. Each button represents a unique input or character, such as numbers, letters, symbols, or special functions.
4. Things that you will get with this models:
2. Well soldered circuits
3. PPT
4. Metal latch
5. Battery
5. Project Price
You can buy this project at price 1500 Rs
You can also customize your project according to your requirement as below:
The price of this projects depend on the component used in the model, for example in the above model the component used is:
2. Key pad module
3. Battery for power supply
4. Door lock
5. Servo Motor
6. Connecting wire
7. Other small component
There are some other optional component available that you can remove or add it to the model according to your need, so the price of the project will decrease or increase according to price of component and coding for example:
1. With display:
You can also add display to this project to show the password entered by user as visual feedback to user, with this component the price of project is 1650 Rs.
2. With LED:
Instead of using display you can also you LED like while the password entered by the user is wrong then red led get ON else if the password is wrong then green led get ON else yellow led to show circuit is in working condition, with these components the price of project is 1450 Rs.
3. With LED and display:
You can add LED and display both in the project for more informative feedback to user by Arduino, so it will be convenient to use and attractive, with these components the price of project is 1865 Rs.
In summery, you can tell us what functionalities and components that you want to add or remove from the model, so the price will change accordingly. If you have any question related to this project then contact me: click here
