HOW DOES AN ULTRASONIC SENSOR WORK?

"Edit: On 1:26, the Echo pin is the one which receives the sound waves and the Trigger pin is the one which emits the sound waves.
In this video, we talk about what an ultrasonic sensor is, how it works and what are its applications.
An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object's proximity.
Applications:-
It Uses to avoid and detect obstacles with robots like biped robots, obstacle avoider robots,
pathfinding robot, etc.
Used to measure the distance within a wide range of 2cm to 400cm.
Used to map the objects surrounding the sensor by rotating it.
Depth of certain places like wells, pits, etc can be measured since the waves can penetrate
through the water.

1:19 its wrong please share accurate knowledge

[@unitedrobotics7377]

Please make a video on esp 32

[@RobuInlabs]

Hey, yes will do soon!

[@unitedrobotics7377]

@@RobuInlabs thankyou !!

[@humourme2442]

Most of things in robu .in is out of stock when are you going to restock??

[@RobuInlabs]

Hey, sorry for the inconvenience, please do check now if the products that you are looking for are back in stock. If not, they most probably will be soon. :)

[@skpatel0347]

When will fs i6 transmitter will availabe

[@RobuInlabs]

Hey, they will soon be available. The Lockdown has been re-instated here so it might take a little time. But we will update you once it does :)

Dear,
You have made a video on hand sanitizer dispenser. I don't know that how to copy paste code or programme an arduino that you have uploaded on your blog page.. So its a request from you to tell me that how can i do that??

[@RobuInlabs]

Hey, we quite aren't able to understand the issue. But from what we're guessing, you just copy the entire code (drag cursor from start of code to end) and paste it in you Arduino IDE.
If this doesn't answer your problem, please let us know

@@RobuInlabs ok Thanks

Dear, its a humble request from u to make a video on programming of this code or tell me in detail that how can i paste all these codes of sensor and relay module and for dispenser at the same time... Please make a short video on it and post it publicly or private and share a link with me. God will surely bless u... Its an urgent project for me. Please🙏

[@RobuInlabs]

@@_das_deepak_ Copy the code from our blog and make multiple sketches in Arduino IDE. Paste codes in separate sketches. for example, the relay module code in a separate sketch, the ultrasonic sensor code in a separate sketch.
Just copy the codes from our blog (the link for the blog is in the description of the video) and paste them in the IDE.
Hope this helps :)
