Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project.

Learn how to use ultrasonic sensor HC-SR04 with Arduino, how ultrasonic sensor works, how to connect ultrasonic sensor to Arduino, how to code for ultrasonic sensor, how to program Arduino step by step.

Aug 5, 2017 · In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Let's get right to it!

Oct 7, 2021 · We provide a schematic diagram on how to wire the ultrasonic sensor and an example sketch with the Arduino. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. This sensor reads from 2cm to 400cm (0.8inch to 157inch) with an accuracy of 0.3cm (0.1inches), which is good for most hobbyist projects.

In this tutorial we will learn how the HC-SR04 ultrasonic sensor works and how to use it with Arduino. This is the most popular sensor for measuring distance and making obstacle avoiding robots with Arduino.

Apr 26, 2024 · In this article, we will study how to design this ultrasonic sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor. In addition to this, we will see the Arduino code written on IDE that will result in a sensor.
