This Arduino code allows you to use an RFID module (model MFRC522) to create a door lock system. The code includes functionalities to write a code to a specific block on an RFID card and to read the ...

IMPORTANT NOTE: The RFID module's pins MUST align with the pins shown in the diagram if using a Mega 2560R3. These pins are dedicated SPI pins by the CPU. See the graphic for the necessary pinouts for ...

In this Arduino based Solenoid door lock project we use a real Solenoid Door Lock and control it with RFID and Arduino. Here a Hall Effect sensor and a magnet are used to detect the door movement.

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 ...

RFID Door lock system using Arduino Before building our password door locking project, first, we need to collect the required components and then go ahead and follow the step by step building process.

This is an IoT-based system with Radio Frequency Identification System which supports door lock and unlock function. This door locking system helps registered users to lock or unlock the door. The ...

In this tutorial, the presenter will be giving you a tutorial on radio-frequency identification (RFID), how it works and how to make an Arduino based RFID door lock. It’s a non-contact technology that ...

An RFID reader and Arduino run the system, with a button inside to unlock the door. But if power were to fail, you will still be able to get in or out manually.
