In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
