Overview of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System is a comprehensive security solution for residential and commercial applications. It combines the use of an RFID card reader, a fingerprint scanner, and an electronic door lock to provide a secure and reliable access control system. The system is designed to be user-friendly and easy to install, requiring minimal technical expertise.
Technical Specifications
The system is powered by an Arduino board, which is connected to the RFID card reader, the fingerprint scanner, and the electronic door lock. The RFID card reader is connected to the Arduino via red and yellow wires, while the fingerprint scanner is connected via white, green, and blue wires. The VCC and Ground pins of the PN532 RFID module are connected to the Arduino’s VN and Ground pins, which are in turn connected to a 5V and 3A regulated power supply.
How the System Works
When the system is activated, the user is prompted to scan their RFID card. Once the card is scanned, the user has 15 seconds to complete the biometric verification by placing their finger on the fingerprint scanner. If the biometric verification is successful, the electronic door lock will open. If either the RFID card or the fingerprint scan is invalid, the system will reset and the user will be prompted to scan the RFID card again.
Additional Features
The system can be further modified to include additional features, such as a buzzer that will sound if an invalid RFID card or finger is scanned. Additionally, the system can be programmed to log access attempts, allowing for a detailed audit trail of who has accessed the premises.
Overview of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System is an advanced security system that combines the use of RFID and fingerprint scanning technology to provide a secure and reliable way of controlling access to a door. This system is powered by an Arduino microcontroller, which is connected to a PN532 RFID module and a fingerprint module. The PN532 RFID module is connected to the Arduino’s A4 and A5 pins, while the fingerprint module is connected to the Arduino’s digital pin 5. Additionally, a 5V SPD type relay is connected to the Arduino’s VN and ground pins, as well as to the external 5V power supply. This relay is used to control the 12V DC electronic door lock, which is connected to the 12V power supply’s ground wire and the relay’s red wire.
Components of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System consists of several components, including an Arduino microcontroller, a PN532 RFID module, a fingerprint module, a 5V SPD type relay, and a 12V DC electronic door lock. The Arduino microcontroller is the main component of the system, as it is responsible for controlling the other components. The PN532 RFID module is used to read and write data from RFID tags, while the fingerprint module is used to scan and verify fingerprints. The 5V SPD type relay is used to control the 12V DC electronic door lock, while the 12V DC electronic door lock is used to physically control access to the door.
Functionality of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System is designed to provide a secure and reliable way of controlling access to a door. When a user approaches the door, the system will first scan their RFID tag or fingerprint. If the RFID tag or fingerprint is recognized, the system will then activate the 5V SPD type relay, which will in turn activate the 12V DC electronic door lock. This will allow the user to access the door. If the RFID tag or fingerprint is not recognized, the system will not activate the 5V SPD type relay, and the user will not be able to access the door.
Advantages of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System offers several advantages over traditional door security systems. Firstly, it is much more secure than traditional systems, as it requires both an RFID tag and a fingerprint to be recognized in order for access to be granted. Additionally, the system is much more reliable than traditional systems, as it is powered by an Arduino microcontroller, which is highly reliable and durable. Finally, the system is much easier to install and maintain than traditional systems, as it only requires a few components to be connected and does not require any complex wiring.

Overview of Arduino RFID and Fingerprint Door Security System
The Arduino RFID and Fingerprint Door Security System is a comprehensive security system that combines the use of RFID and fingerprint sensors to provide an extra layer of protection for a door or other entryway. The system is easy to install and use, and requires the installation of two libraries: the Fingerprint Sensor Library and the Liquid Crystal I2C Library. The program is then uploaded to the Arduino board, and the system is ready to use.
Installation of Libraries
The installation of the libraries is straightforward and requires downloading a WinRAR file from the website Electronicclinic.com. The file contains all the required libraries, which must be copied and pasted into the Arduino libraries folder. Once the libraries are installed, the program can be uploaded to the Arduino board.
Programming the System
The programming of the system is not complicated and involves combining two projects. The user must watch the getting started videos on the R557 Fingerprint Sensor and the PN532 RFID Sensor, as they will need to enroll their finger in order to use the finger ID. The instructions are well-commented and should not cause any issues.
System in Action
When the system is activated, a message is printed on the LCD stating “RFID Card is printed on the LCD”. The user then has 15 seconds to complete the biometric verification. If the user does not place their finger within the allotted time, the message “Access Denied” is printed on the LCD. If the user does place their finger, the message “Access Granted” is printed on the LCD.
