Arduino Ultrasonic SONAR with SG90 Servo | Kitkraft DIY Distance Detection System

When it comes to learning and experimenting with electronics, nothing beats the excitement of building your own DIY projects. In this blog, we’ll guide you through creating an Arduino-based Ultrasonic SONAR system that uses an HC-SR04 ultrasonic sensor and an SG90 servo motor to measure and detect objects in its surroundings. This project is not only educational but also a fantastic introduction to robotics and automation for enthusiasts and students alike.


What is a SONAR System?

SONAR (Sound Navigation and Ranging) systems use sound waves to detect objects and measure distances. In this project, we simulate a SONAR system with an ultrasonic sensor and a servo motor. The ultrasonic sensor sends out sound waves and detects the time it takes for the waves to bounce back from an object. This data is then processed by an Arduino Nano to calculate the distance and display it in real-time.

Additionally, we’ll be using the Processing application to visualize the data as a real-time radar interface.


Components You’ll Need

To get started, gather the following components:

  • Arduino Nano

  • HC-SR04 Ultrasonic Sensor

  • SG90 Servo Motor

  • Breadboard

  • Jumper Wires

  • USB Cable for Arduino

  • Computer with Arduino IDE and Processing installed

All these components are readily available at KitKraft.in. Order now and start building your project today!


How Does It Work?

  1. Ultrasonic Sensor: The HC-SR04 emits ultrasonic sound waves that bounce back when they hit an object. By calculating the time taken for the sound to return, the sensor determines the distance of the object.

  2. Servo Motor: The SG90 servo rotates the ultrasonic sensor, enabling it to scan its surroundings and measure distances at different angles.

  3. Arduino Nano: The Arduino processes the data from the ultrasonic sensor and sends it to the Processing application for real-time visualization.

This combination effectively mimics a SONAR system, providing a 2D map of nearby objects.


Circuit Diagram and Wiring

Here’s how you can wire up your components:

  • HC-SR04 Ultrasonic Sensor:

    • VCC: Connect to 5V on the Arduino

    • GND: Connect to GND on the Arduino

    • Trig: Connect to digital pin D9

    • Echo: Connect to digital pin D10

  • SG90 Servo Motor:

    • VCC: Connect to 5V on the Arduino

    • GND: Connect to GND on the Arduino

    • Signal: Connect to digital pin D3

Ensure all connections are secure and double-check your wiring before powering up the circuit.
