If you’ve worked with passive RFID before, you know that most readers ... by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output.

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.

The project relies on the built-in Wi-Fi module of the Arduino Yun, and the microcontroller is connected to the sensors and RFID reader modules alongside an electronic strike to lock/unlock the door.
