[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.

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

Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar ... like the BME280 environment sensor, RC522 RFID module, and TFT display module.
