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.

In this project I have created a code for an Ultrasonic Sensor in the Arduino IDE. If an object is present within 10cm of the sensor then buzzer will work.

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 ...

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 ...

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 ...
