DIY Smart Lock with Arduino and RFID
In this project, I have used an RFID reader (MFRC522), Arduino microcontroller (Mega 2560), Arduino programming lanuage 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 an 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
