For this project, the following will be needed:

Arduino Nano with USB cable Amazon

On/Off Switch Amazon

9V Battery or 5V Power Supply

2 SG90 Servos Amazon

RC522 RFID Module Amazon

At least 2 RFID tags

Soldering iron and supplies Amazon

The Arduino Nano is a microcontroller board that is based on the ATmega328. It has similar functionality as an Arduino Uno but has a tiny footprint (18 x 45 mm) which makes it great for projects that need to be smaller in size like my RFID lock box.

For the RFID functionality I will be using an MF RC522 which is a highly integrated read and write card chip applied to the 13.56 MHz contactless communication. It is a low voltage, low-cost ($1.6 on AliExpress), and small sized non-contact card chip. I will be using a few RFID tags to control the locking/unlocking mechanism of the box.
