Arduino UNO/Nano/Mega operates at 5V logic. However, the MFRC522 works at 3.3V logic level, and is not 5V tolerant. If using one of these microprocessors: The solution to both a.) and b.) is trivially ...

In this tutorial we are going to design a system to read the ID of RFID cards. RFID stands for Radio Frequency Identification. Each card has a unique ID embedded in it. These systems have many ...

Radio Frequency Identification is widely used in contactless payment cards, National Highway Tollgate systems, and in security passes. By integrating an RFID reader with an Arduino, you will be able ...

This RFID Based Access Control System is built around Arduino UNO board, RFID reader module, solenoid lock and a few other components. RFID is a non-contact, automatic identification technology that ...

The setup Consist An Arduino UNO (any varient will just work great with an Ethernet Sheild or Module) Arduino Ethernet Sheild. Pizzo LED Some Connecting Wire This part is pretty Simple. Put an ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

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 ...

Arduino RFID projects have become increasingly popular in recent years due to the simplified technological mechanisms provided by the Arduino platform. The integration of RFID technology with Arduino ...
