Description This Arduino project uses an HC-SR04 ultrasonic sensor to measure the distance to an object and visually represents this distance using an array of 8 LEDs. Additionally, a buzzer is used ...

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 is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

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?

Abstract: An advanced blind assistance device integrates an ultrasonic sensor, Arduino UNO board, buzzer, and GSM module to create a cost-effective solution for enhancing the safety and autonomy of ...
