To calculate the distance from the ultrasonic sensor, We just need to write Arduino code to do two steps (1 and 6 on How It Works): Arduino Nano generates a 10-microsecond pulse on the TRIG pin. Arduino Nano measures the pulse duration in the ECHO pin.

Nov 8, 2022 · In this Arduino project, let us learn how to interface HC-SR04 ultrasonic distance sensor with Arduino to build an Arduino Distance sensor and display the distance measurements on a 16X2 LCD display in centimeters and inches.

Apr 30, 2024 · In This Article, We will learn how to measure the distance using an Ultrasonic sensor & Arduino. It is an open-source electronics platform. It consists ATmega328 8-bit Microcontroller. It can be able to read inputs from different sensors & we can send instructions to the microcontroller in the Arduino.

May 10, 2021 · DIY distance measuring device using HCSR04 ultrasonic sensor. How Ultrasonic Sensor works- Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound.

Jan 12, 2019 · The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino.

Distance Measuring with HC-SR04 and Arduino. This project demonstrates how to measure distance using the HC-SR04 Ultrasonic Sensor and Arduino. The distance is measured in real-time and can be displayed on an LCD or serial monitor. It's perfect for beginners in electronics and Arduino enthusiasts looking to understand how ultrasonic sensors work.

Feb 2, 2025 · In this project, we use HC-SR04 Ultrasonic Distance Sensor with Arduino for displaying the measured distance on an LCD screen. The HC-SR04 sensor operates on the principle of sonar, emitting an ultrasonic wave at a specific frequency that reflects off an object and returns to the sensor.

Aug 28, 2022 · How Does HC-SR04 UltraSonic Sensor Work? Ultrasonic sensor is use to calculate the distance. It use ultrasonic waves to measure the distance. The ultrasonic wave can hit the object and and come back, ultrasonic sensor can use time to calculate the distance. HC-04 consists of two ultrasonic transducers.

Jun 4, 2020 · This tutorial will guide you through wiring the HC-SR04 to an Arduino, writing code to measure distances, and triggering an LED when an object is nearby. You’ll also learn the physics behind ultrasonic sensing and how to adapt the project for real-world scenarios.

In this section, we will design a distance measurement meter using an HC-SR04 ultrasonic sensor and Arduino. We will use a 16×2 LCD to display the measured distance value. In our previous tutorial, we posted an in-depth guide on 16xLCD interfacing with Arduino.
