Parking Sensor

This sketch and suggested hardware ties together a cheap
TM1638 based display and an off the shelf ultrasonic sensor
to create a device that tells you how much further you need
to go to be parked.

It's definitely a toy - something that would have traditionally
been accomplished by "winging it" when parking, or using a string
and a ping pong ball affixed to the ceiling. But when some of the
electronic parts are so cheap these days, why not have a little
bit of fun with it?

See the supplied Fritzing file for the very simple schematics.


This project would not be possible without the following two
Arduino libraries. Thanks to the authors who made their work
available! (v1.5 or greater)
