In this project, we will build a simple Access Control System using RC522 RFID Module, Arduino and MG 996R Servo Motor. Authenticate people using their RFID Smart Cards or Key Fobs and allow them ...

In this project, RFID-RC522 is interfaced with Arduino and then RFID data is sent to Tkinter GUI and MySQL database using Python. It also uses sensors like DHT11 to collect, plot on GUI, and save to ...

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 ...

RFID technology identifies objects using a unique identifier through an RFID tag and reader system. RFID tags can be read-only, with fixed identifiers, or read and write, allowing information updates.

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 ...
