This project will help the driver to park his car without hit the wall. The main component of this garage parking project is PING Parallax ultrasonic sensor and Basic stamp microcontroller. The Garage Parking Assistant makes it easy to pull in the garage by signaling the driver with a traffic-light style display of when to pull in (GREEN), slow down (YELLOW) and stop (RED). If the driver pulls too far in, the Red LED will blink to warn the driver.
