Arduino based garage parking sonar

Mike seeing how mother struggles to park her giant car in to garage decided to build simple parking sonar that would make her life easier. He chosen several ready to use components like Ultrasonic Range Finder, Arduino, tricolor LED and several other components.

The idea was to build sonar stationary on garage front wall which would detect distance to car. As indicator he connected RGB LED and placed it so the driver could see while parking. With three colors it is easy to track distance. Green is OK, Blue – slow down; RED – Stop. No more scratched bumper!
