Description This smart sound alert system illustrate the potential of using Arduino, buzzer and ultrasonic sensor in building a security system. Use case Creating a smart alarm system. Step 1: The ...

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.

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

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 ...

Abstract: The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the ...
