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?

Hardware

See the supplied Fritzing file for the very simple schematics.
