Introduction: DIY Range Finder With Arduino

About: Hi, I am a student i love to create different projects its my talent and i love to invent something cheaper ...

In this article i will show you how you can make an range finder using arduino.

Step 1: Connect the LCD Display to Arduino

Now you need to connect the lcd module to the arduino and make it ready for programming and move on to the next step.

Step 2: Programming

Now connect your arduino and its time to program it.

First you need to download the provided libraries files and paste them into the arduino libraries folder after that you need to upload the address scanner code to arduino and you will get your address i2c code and then upload the final code to arduino and don't forget to change the address code as shown in above.

Move on to Step 3.

Step 3: Wiring the Circuit

Now you need to wire the whole circuit according to the diagram and move on to the step 4.

Step 4: Creating a Box

I made a box using a 3d printer as shown in the pictures you can use any plastic box as well.

Step 5: Placing Components

I place all the component in there place as shown in the pictures.

Step 6: Ready to Use

Now our project is complete and it is ready to use now. Turn on your range finder and find any range or distance.

There is minor ±1 cm error in the program which can be ignored. Hope you enjoy making this project.
