Introduction: How to Build an Arduino Ultrasonic Range Scale: a Comprehensive Guide

By

Are you interested in making Arduino projects but not having proper explaination and stucks in middle of your project? Don't worry this time you are in the right place.


  • Grab your Arduino board, gather your components, and let's dive into the fascinating world of ultrasonic sensors and distance measurement.


  • By the end of this guide, you'll not only have a fully functional range finder but also a deeper understanding of how it works and the endless possibilities it opens up for future projects.


  • Without further wasting our time, let's get started!

Supplies

here are basic components required to build our project:

  1. 1X Arduino UNO
  2. 1X Ultrasonic Module HC-SR04
  3. 1X IIC/I2C LCD Display Module
  4. 1X Buzzer Module
  5. 1X 9v Battery
  6. 1X Switch

Other Essential Things Required during working on this project:

  1. Jumper Wires
  2. Arduino UNO Cable (For Programming)
  3. Soldering iron (If Required)
  4. Glue
  5. Small foam piece

Step 1: Follow Circuit Diagram and Connect All Electronics

Althought it was pretty easy Connections you might not having any issue in it. you can use Breadboard also to further simplify conections

Here you can Download Circuit Diagram.

Step 2: Let's Start Programming the Arduino Board

here is the Arduino code

REMEMBER: YOU HAVE TO INSTALL SOME LIBRARIES TO UPLOAD CODE (LIQUID CRYSTAL, WIRE, NEWPING)

you can download it from internet then copy all libraries and paste in : Documents>Arduino>libraries

or you can directly install from arduino IDE by click on: sketch > library > manage library

Step 3: Now After Sucessfully Uploading Code We Have to 3D Print Cabinat

If you don't have CNC machine you can use any other materials also Like: PVC, Cardboad ,etc

Note my words: You own this you can make changes of your choice

Step 4: Put All Components in 3D Printed Cabinet

After Fitting Components Inside 3D Printed Box Take A Foam Piece And Put It In Remaining Gaps To Avoid Shaking And Damaging Wiring In Future

Step 5: Congratulations...your New Project Works Successfully

This Works Very Well And Pretty Accruate For Daily Uses.. We Can Add A Potentiometer To Further Increase Accuracy.

But For Now This Is A Fantastic Project For Learning...Hope You Earned Some Valuable Information By Working With Us.

I Am Very Happy To Share My Knowlwdge With You

Have A Great Day Makers ;)
