Garage parking sensor
Parking into a garage can be very difficult task for some drivers. Instead of an old trick with a tennis ball hanging off of the wall, a clever little device is built that allows driver to park his car just right.
The main component of this device is PING))) Parallax ultrasound sensor and Basic stamp (PIC) microcontroller. There are three LEDs on this "parking helper" that display current position of a car in a garage. Green LED marks parking zone, yellow LED warns driver to slow down and red LED marks the stop-zone. When red LED blinks that means that the driver is too close to the wall and should back up a little.
