An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

A second Arduino is used to read NFC and RFID cards using a Mifare RC522 reader. The system uses its own credit system, so a user can be issued a card with a certain amount of pre-paid credit.

– MFRC522 connection header: This is where the MFRC522 RFID reader connects to the main board. – Program select header: Currently, only header#1 is being used in the program.
