Arduino Garage Parking Sensor

This is my implementation of a parking sensor I saw here:
• How to make an Arduino...
It's the same idea with the same basic parts, I've just made a few tweaks and made it a permanent fixture in my garage. The plastic parts were designed in fusion 360 and cut from 2.5mm acrylic on my K40 laser and superglued together.
