If the serial number matches an entry in the allowed list, the system can activate a relay to open a gate or send a signal to a display indicating successful authentication. You need to install specific libraries, such as the MFRC522 library, which provides the necessary functions to initialize the reader and authenticate the tags.
Arduino RFID Sensor Signal Interpretation Guide
The Arduino board serves as the central processing unit, handling all the logic and decision-making tasks. The core functionality of an Arduino RFID sensor revolves around the communication between a reader module and a transponder.
3V GND GND Programming and Logic Implementation Once the hardware is connected, the software logic determines how the system interprets the RFID signals. Arduino Uno or Mega microcontroller board RFID Reader Module (such as RC522 for Mifare cards) RFID Transponder Tags (Tags or Cards) Jumper wires for establishing electrical connections Breadboard for prototyping the circuit without soldering Pin Configuration and Wiring Correct wiring is critical for the sensor to communicate with the Arduino board.
