This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

This project involves building an Arduino-based auto-driving car that utilizes ultrasonic sensors to detect obstacles and make decisions on movement. The car can be started using a push button, and it ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?
