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.
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.
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.
