How to design a smartphone Circuit Diagram Here, we'll focus mainly on the newer NFC standard for RFID chips, and its applications to access control within smart door locks. NFC Smart Locks: How They Work The Tech in NFC Smart Locks. As we've covered the science behind NFC tech in the article referenced above, here we'll mainly discuss its applications in Smart Locks. The system consists of an Arduino Uno microcontroller, an MFRC522 RFID/NFC reader, an SPDT relay, and a 12V DC solenoid door lock. The RFID/NFC reader reads the UID of the tag and compares it with a pre-defined UID in the code. If the UIDs match, the system triggers the SPDT relay to unlock the door for a pre-defined time period, allowing access. Building a smart door lock using a Raspberry Pi is an exciting and rewarding project that can enhance the security and convenience of your home. Throughout this guide, we have explored the step-by-step process of creating a smart door lock, from choosing the right hardware to programming the Raspberry Pi and assembling the components.

Hello guys, Welcome to Robocraze! In this video, we have shown the Making of the Smart Security Lock System using the Witty Fox NFC module and Solenoid Lock.
Arduino RFID 'Smart Door' Tutorial : 7 Steps Circuit Diagram
RFID is useful to identify people, to make transactions, etc. You can use an RFID system to open a door. For example, only the person with the right information on his card is allowed to enter. In this tutorial, we have multiple RFID tags, each with its own Unique Identification (UID) but only one card will be granted access. RFID-RC522 Pin Layout Here's what you'll need to create your smart door lock system. Smart Lock Mechanism. Start with a smart lock mechanism that forms the core of your setup. This component includes the locking mechanism, connectivity features, and compatibility with smart home systems. When it comes to selecting the appropriate smart lock technology for
