Project No. 01: Creating Door Lock system With Radio Frequency Identification (RFID)

1. Introduction: 

The Arduino RFID door lock project combines the power of Arduino microcontrollers and Radio Frequency Identification (RFID) technology to create a secure and convenient access control system. RFID technology allows for contactless identification using radio waves, making it an ideal choice for door lock systems. By integrating an RFID reader module with an Arduino board, we can authenticate users based on their unique RFID tag IDs and grant them access to a locked door.

The primary goal of this project is to design a door lock system that eliminates the need for traditional keys or keycards, offering a more modern and efficient solution. With RFID technology, users simply need to hold their authorized RFID tags near the RFID reader to initiate the authentication process. The Arduino board, acting as the control center, reads the unique ID from the RFID tag and compares it with a list of authorized tag IDs stored in its memory. If a match is found, the door lock mechanism is activated to unlock the door temporarily, allowing authorized users to gain entry. 

2. Working: 


Step1: Initialization
The project begins by using an RFID reader module connected to the Arduino board. The RFID reader emits radio waves to detect nearby RFID tags. When an authorized RFID tag is brought into proximity with the reader, it energizes the tag's circuitry.


Step2: Authentication 
Once the RFID tag is energized, it sends back a unique identification code embedded within the tag's memory. The RFID reader captures this code and sends it to the Arduino for processing. The Arduino compares the received RFID tag ID with a list of authorized tag IDs stored in its memory. It performs a matching operation to determine if the presented tag is authorized for access.


Step3: Verification 
Based on the comparison result, the Arduino executes a decision-making logic. If the tag ID matches an authorized ID, the Arduino proceeds to unlock the door. Otherwise, access is denied, and the door remains locked. The Arduino controls the door locking mechanism, such as a servo motor or an electric strike, based on the decision made during the authorization process. When access is granted, the Arduino triggers the unlocking mechanism to temporarily unlock the door, allowing authorized individuals to enter.

3. What is RFID module?

An RFID module, also known as an RFID reader module, is an electronic device that is capable of reading and interacting with RFID tags. It typically includes components such as an antenna, a transceiver, and control circuitry.

The RFID module acts as an interface between the RFID tags and a larger system. It captures the data from the tags and passes it on to another device, such as an Arduino, for further processing. It also provides necessary functionalities to control the operation of the RFID reader and tags, such as setting read parameters, initiating tag detection, and managing communication protocols. In summary, an RFID module is a device that facilitates communication between RFID tags and other systems by providing the necessary hardware and control functionalities for reading and interacting with the tags.

The project can also work without display it is used to show visual command, so user understand what is happening, with this component the price of project is 1500 Rs. 

2. With LED : 
Instead of using display you can also you LED like while there is no tag near the device the red led will be ON and yellow led to show power supply to circuit is ON and after the user get verified the green led will get ON and lock will get open, with this component the price of project is 1500 Rs.

3. With key pad: 
you and add key pad for manual password entering so that the person who don't have RFID can also access the room with there unique password, with this component the price of project is 1700 Rs.

4. With Key pad and display both: 
 you can use both key pad and  display for making you project more convenient to use and user friendly, with these components the price of project is 1900 Rs.

5. With RFID module only: 
If you want to use only RFID then with this component the price of project is  1400 Rs.
