Description of the “RFID Security Access System using Arduino” project

RFID based security system using Arduino project has an RFID reader attached to it. RFID reader reads the unique alphanumeric code of RFID tags and sends it to Arduino. Then Arduino detects whether an RFID card is valid or invalid. If the card is invalid then the system turns on the buzzer. However, if the RFID card shown by the user is valid then the DC motor is turned on and at the same time Relay is turned on. DC Motor is shown as a demo of a door lock (latch) opening. Also, a Relay is provided as an additional feature so that the user can connect any electromagnetic security lock to the system if required.

There are various electronic security systems such as Password-based security systems and Fingerprint based locking systems. Arduino-based RFID access control system provides us with the feature of an automated access control system. Arduino security system provides keyless entry to the house/office.

Description in detail:

This is one of the most important projects amongst all Arduino Projects For Final Year Students. And following are the important modules in this project:

1. Arduino: It is the main processing unit of the project. It controls output devices, it also reads input from the RFID reader. Arduino sends various messages to LCD displays.
2. RFID reader: It detects the card and sends 12 digit alphanumeric unique code on the serial port
3. DC motor: It is used to show a demonstration of door or gate opening. Motor driver IC is used to drive the motor.
4. LCD Display: 16 by 2 Liquid Crystal Display (LCD) is used in this project. It displays on 2 lines each containing 16 characters.
5. Relay: 12-volt relay is used. The relay driver circuit is used to turn on the relay. Using this relay user can control any AC or DC device.
6. Buzzer: We have used a piezoelectric buzzer. This is a warning/indication that an invalid attempt is made to gain access to the system.

Applications Advantages of RFID based security system using Arduino:

1. This project can be used in schools or colleges. We can also use this project in industries and offices.
2. We can use this project in our home as well.
3. This project is fully automatic and does not require any manual operation.

Future Development of the project:

1. We can add a voice alert system to the Arduino based security system using an RFID reader.

Questions and answers about this project:

Question: Can we use a Stepper motor in place of a DC motor?

Answer: Yes, you can. However you need one more connector from motor driver IC. Reason: DC motor has 2 pins to control whereas Stepper motor requires 5 (or 6) pins
