Thanks bro 👍👊👌

Good explanation

[@techathome]

Thank you

make another 20 parts, very nice videos

[@techathome]

Thank you. We will make more..
There are around 30 video as of now : th-cam.com/play/PL4B0LEKY-jrT_fjOGkX_NZ52ZHZf8s9S-.html

Hello, I have the same problem with LET’S UNBOX!, as you have stated, I checked the pins and replaced all the jumper wires, but it still does not work, it keeps repeating “0”. Would you possibly know what else is the problem?

[@techathome]

This issue is because, signals from sensor are not reaching Arduino pins,
- Check wire
- Check connections
- Replace sensor

[@anithasshenoy6662]

Thanks for this video. I am not getting anything from the pulseIn() . Hence the distance is showing zero. I have two new modules. Both show the same result. What could be the reason ?

[@techathome]

Check the continuity of jumper wires, sometimes they will be faulty.

[@anithasshenoy6662]

@@techathome I removed it from breadboard and connected directly. Now it is working. thks

[@kirans9395]

Why have you divided by?
Due to 2 microsecond delay?

[@krk101]

We need half of the time taken by the sound. We get the total time, sensor to object and back. But we only need time taken to reach the object. So it's half.

[@techathome]

Unplug and replug again and try.
Also plug it to different com port.

Bro its emergency can we write the same program for the project train accident prevention if not can u pls say the procedures how to write tomorrow is my science expo only the coding is pending can u pls help bro plssss

Can u send request on mail, I am not completely clear with your project requirements: [e-mail]

can you explain the formula bro
why should we divede it by 9?

[@fusionworld6871]

Bro.
I am getting some values and o in between the values ..

[@techathome]

If you are not inside its range,
It will give some random values

[@Bigbrainie]

Can we print the distance on lcd instead of serial? Where should I make the changes in code?
If possible, please make a video.
I am a beginner :-)

[@techathome]

We have done tutorial on that, you can refer to below two video links:

[@muninggamer7621]

how to increase the range of the ultrasonic sensor?

[@techathome]

It is not possible to increase the range with software.
It depends on the specifications of ultrasonic sensor.

[@Bigbrainie]

I'm getting distance 0 on serial monitor everytime. What to do?

[@techathome]

Check the pins connections of ultrasonic sensor and also replace the jumper wires

Your formula is wrong and is not working properly

in second last line you haven't use semi colon ;

Oh, my be we have to update the code file

[@yamanjain9346]

Do you all were able to here audio after 3:42

[@techathome]

I checked now,
Everything was fine before,
Last week there was some copyright issue for background music.
So we removed that.
Somehow this explanation voice also got deleted.

the thing that shows the distance doesnt show up

[@techathome]

I didn't get your question.

[@scout3526]

Bro some 800 , 1000 values are getting displayed how to avoid those values .?

[@techathome]

If you go beyond the range it gives random values sometimes. This is basic code to understand the working. Use ultrasonic library, this issue might resolve. Download and install this one: downloads.arduino.cc/libraries/github.com/ErickSimoes/Ultrasonic-3.0.0.zip
