Build An Arduino Parking Assistant

Those of us who have small garages know the frustration of parking a little bit too far in or a little too far out and not being able to walk around the vehicle. We recently bought a larger vehicle, and it has to be parked perfectly in the garage to walk around the front and back.

Arduino Parking Assistant



To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working with Arduinos, leds, sensors, and nearly anything else electronic, so I knew from the start that it would probably end up as a contraption with an Arduino inside and a bunch of LEDs on the front!

I tried my best to document every step of this project well, but please note that it has some complicated, tight soldering; it probably shouldn’t be your first project.

Step 1: You Will Need…

All of these materials are cheap and easily available. I’m not affiliated with any of these suppliers, they’re simply where I bought the supplies.


  • 1x 2×4 – at least 8″ long
  • 8x Philips Screws – Preferably 1″ Long
  • 1x Power Supply – 5 volt, 850mA Here
