The RX pin is not required as we do not send data to the RFID module in this tutorial. Lastly, connect the antenna to ANT1 and ANT2 pin in any polarity. Programming Arduino for RDM6300 RFID Reader.

This comprehensive Arduino RFID tutorial teaches you how to interface RFID (Radio Frequency Identification) technology with Arduino microcontrollers using the popular RC522 RFID module.Arduino RFID ...

RFID Not Detected: Check connections between the RFID module and Arduino.Ensure correct wiring of SCK, MISO, MOSI, and SDA pins.; Incorrect UID: Ensure the RFID card's UID matches the one stored in ...

The code is developed using the Arduino IDE. The EM 18 RFID module operates on serial communication; when RFID is detected, it sends the data over serial pins. Here, the Arduino hardware serial pin RX ...

Arduino/ESP32 code for R200 long-range UHF RFID reader. The R200 is a UHF RFID module based on the EPC Gen-2 (ISO18000-6C) protocol. What does that mean in practice? Well, it can read up to 60 tags ...

RFID reader module. In this project, we used EM-18 RFID reader module (Fig. 2) operating at 125kHz. The module comes with an on-chip antenna and can be powered with a 5V power supply. The transmit pin ...

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.
