Distance Meter / Range Finder using Arduino Uno & HC -SR04 ultrasonic sensor || Arduino Project

Hello friends,
In today's video I am going to show you how to make a distance meter using Arduino Uno & HC -SR04 ultrasonic sensor. The distance meter is used to measure very accurately the distance to different objects. The range of measurement is also very high upto 4 metres. This can also serve as a range finder.
In this video, I am also showing the comparison of the measured distance using the distance meter and a standard measuring tape.

Great project, good detailed description. I really like the comparison you did with the ruler to test the accuracy of the ultrasonic sensor. Keep up the great work! I subscribed to your content, looking forward to more of your innovative videos.

It doesn't show 0 and 1cm, it shows some random no like 1191cm, what should we do?

[@Science_4U_]

Hi friend. That is most probably because the ultrasonic sensor that you have used is faulty. Replacing the sensor should solve the problem..

why does it give me an error?

[@Science_4U_]

Hi friend. What is the error that it is showing?

[@user-xx5vq6mf3f]

im all right but it doesnt give me an out put

That is correct friend. That light blinking according to clock ticking will make it more interesting. .
