A small tutorial for interfacing a ultrasonic sensor with arduino this uses a sensor called HC-SR04 which sends ultrasonic waves to detect objects in front of it.

The complete Arduino Levitation circuit is shown below and the working principle of the circuit is very simple. The main component of this project is an Arduino, L239D motor driving IC, and ultrasonic ...

This project implements a rotating ultrasonic distance scanner using an Arduino, an HC-SR04 ultrasonic sensor, and an SG90 servo motor. Distance readings are transmitted over serial and visualized in ...

Arduino UNO: As you know, Arduino is a microcontroller-based open source electronic prototyping board that can be programmed with an easy-to-use Arduino IDE. The UNO is one of the most popular boards ...

Ultrasonic sensors utilise sound waves to measure distances, contrasting with infrared sensors that rely on light. The sensor operates by emitting an ultrasonic wave that reflects off an object, ...
