Quickly, he started thinking to himself, “Hmm…I wonder if I could do this with an Arduino Nano?” We’ve all probably had similar thoughts, but [Peter] really put his theory to the test.

In fact, it's only slightly larger than Arduino's smallest board, the Nano, at 51 mm x 21 mm. Both boards are excellent options for circuit building and prototyping, but are there any differences ...

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.
