An ultrasonic parking sensor project from Ch00ftech:
After electing to use the PING))) sensor exactly as directed, I needed to build the rest of my circuit. I wanted to build something robust that would mount nicely on the wall of my dad’s garage. Figuring that the sensor would likely need to be placed down low by the car’s bumper, I decided on a two-component design consisting of a small sensor and a large visible display that could be mounted at eye-level.
