Learn how to build an RFID door lock system using Arduino for secure and smart access control. This step-by-step guide covers circuit connections, coding, and hardware setup to create an automated ...

Here We are going to connect Arduino UNO, RFID (MFRC522) & Ethernet Shield with MYSQL Database. So for that first we should connect our Arduino Board with the Ethernet Shield & RFID Module. By using ...

This project demonstrates how to use an RFID RC522 module with an Arduino to authenticate RFID cards. The system turns on a green LED if an authorized RFID card is scanned and turns on a red LED and ...

Using the RFID starter kit from Elektor provides a good basis to carry out numerous electronic experiments with the Arduino Uno. We show just how simple it can be to realize an application.

RFID enables wireless data collection by readers from electronic tags attached to or embedded in objects, for identification and other purposes. This article describes the construction of a simple ...

The RFID system consists of two main components: an RFID tag and an RFID reader.The RFID tag has different formats. It can be a sticker like the one placed on supermarket products to prevent theft, on ...

By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come up with a method of triggering a device (like an electronic door lock) only when the appropriate combination of RFID ...
