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 gets smaller, the buzzer sounds faster to warn the driver that the objects at the rear of the vehicle are nearer. The aim of this little project is to show how the ultrasonic sensor module can be used in a project to measure distance.
