🚀 Project intro

In this project, I have used an RFID reader (MFRC522), Arduino microcontroller (Mega 2560), Arduino programming language and other components to create an RFID-based smart lock. This lock is a small version of an automated RFID-based smart lock, an important component of an automated home.

🧩 Components

  • Arduino. I've used a Mega 2560, though any Arduino board or clone will suffice.
  • 3 x 220 ohm resistors
  • 1 x 10k ohm resistor
  • Logic-level N channel MOSFET
  • MFRC522 module with at least two cards
  • Red, blue, and green LEDs
  • 12v Solenoid ($2)
  • 12v power supply
  • Breadboard and hook up wires
