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 ...

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 ...

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 ...

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 ...

Circuit diagram in proteus Fig.2 Simulation Image in proteus While using proteus software the virtual terminals will act as an rfid reader, where their connection made oppositely; I.e. RXD of virtual ...

[Jason] really wanted to build an RFID controlled garage door opener and decided to turn to Arduino to get the job done. For someone who’s never worked with an Arduino before, he really seeme… ...
