The RC522 RFID reader module makes Arduino RFID integration straightforward, supporting reading, writing, and authentication operations that we'll explore in this tutorial. After mastering these ...

This project is open-source and can be freely used for educational purposes. I demonstrate how to build an RFID-based access control system using Arduino! This project integrates an RFID reader (RC522 ...

Previously we interfaced MFRC522 RFID Module and EM-18 RFID Reader with Arduino. In this tutorial, we are going to interface RDM6300 RFID Reader Module with Arduino Nano. The RDM6300 RFID Reader is ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

The EM 18 RFID module is used to read the RFID tags and devices, and Arduino is used to process the data and set functions like lock, unlock, or authentication. If the correct RFID tag is scanned, it ...

The most common module/breakout board is the PN532 NFC RFID module (v3) by Elechouse. I am guessing that you have an Arduino Uno board handy. Even though most of the available libraries (for PN532) ...

e.g. An ESP8266 or ESP32 c.) Not supplying enough power The 3.3V output from the Arduino is not capable of supplying much power - it is only good for up to ~150mA. If powering several RFID readers you ...

This is called backscattering. The backscatter is detected and interpreted by the RFID reader, which then sends the data to a computer or a microcontroller such as the one with Arduino. Just as a ...

The Arduino board reads the data from the RFID reader, which in turn drives the relays through ULN IC for that particular quantity. Note: At the end of the article we have added the complete video ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.
