if anyone hates on you, it says more about them, i really struggle with the maths, it is what it is, i can't get it, after 50+ years in academia, i simply don't get that type of maths. As humans we have strengths and weaknesses, it's better to make the best of your strengths. I try, i do.

The concept of "we are not going to use canned codes" are exactly why I have watched ALL of these videos, moved on to your python videos and have come back to c++ between video releases. I will definitely have to check out the rest of the coding subjects. the knowledge you are sharing here is priceless.

I want to make a tee shirt, of Paul cringing and holding his breath when uploading the sketch to the arduino.

You forgot 'improved' haha

With the current lockdown a fellow radio ham in our village has been playing with an arduino (he is over 80). He messaged me when he had a problem with it, he had been following one of your earlier tutorials. I was able to get him back on the right track but have also ordered an arduino for myself. I already have a selection of compatible sensors. I have a background in electronic design but have steered clear of microprocessors in my projects. Your videos have been very helpful already and I am already planning some practical applications. Thank you for the huge effort in making the videos, extremely useful.

I love how you connect these lessons with math! I have found the slope "0,0175" for cm and the slope "0,007" for inch.

I got a slope of 0.006. I do believe the important fact you are getting at, is the speed of sound! Great project!! Anyone that hates you for doing the math and explaining how things work can just skate by in life and keep doing it the easy way! There are plenty of us that enjoy learning from you!! Thank you, Paul!!

slope of the line is m=0.00757. Thank you for pushing and making us to think independently. In life, we need to solve our own problems, we are responsible for our lives . The teachers and coaches are only to help us guide. We have to walk our own path.

PAUL: thank you from my heart for all these fantastic videos!!!!!!!!!!! Pls continue this series ❤❤❤

Hi Paul, thanks for all the tutorials, they are great. Here in Austria, the equation is y = 0,0174x + 0,365 [y in cm] // or equals y = 0,0069x + 0,1437 [ y in inches] thanks for the good work!

No haters are allowed in this house. I REALLY appreciate the use of the oscilloscope in the video. It took me a while to observe the changes in pulse with. I recently purchased a small handheld oscilloscope so this is helping me learn the Arduino side of things and also how to use a new piece of test equipment. Thank you !!

I ended up with .126, but after I read some of your comments (Thanks, gang!), I realized I had to divide for the two way travel and ended up at .063, which is perfect for my distance. Thanks again for all of this, Paul!

Present. I really do love your tutorials and the fact that you're actually teaching me how to do it on my own. I plan on using the knowledge you have provided in order to build my own toys and inventions, kind of hard to copy and paste if it's somewhat original. So yea thank you very much.

Here from the UK. My slope came in at .064inch/microsecond.After your last lesson glad to see my kit is working. Great work Paul. :-)

Love this lesson. We use these sensors to detect the thickness of paper in my equipment. My ruumba also uses them to turn from stairs and not fall down them. I will update on my success with the homework assignment.

The slope I got for inches by µseconds is y = 0,0071x + 0,4424 and for cm by µseconds : y = 0,0179x + 1,1238. Thanks for the tutorials, I really learned a lot since lesson #1. Two thumbs up!

The accuracy of the slope of the line is very important for converting the time data to distance. I did the homework assignment and attached an lcd which shows distance on display. Works perfectly! 👌🙏

Great lesson. Most people never think about how this type of sensor works! I have to set up my sensor circuit on a flat surface and use an appropriate object to bouce the signal to in order to do the calculation, but I will. I'll report back. Again, great lesson!

You are an excellent teacher; If you explain the imperial system the world might adopt it.

Hello, hope you are perfectly happy and healthy! Your video is a great relief, since I have been unduly stressed by the ongoing world drama. I have never been so emotionally negative before. So I pray that you remain in high spirits.

thank you! I enjoy from your videos, you make it clear and comprehensible.

Oh my God, I am enjoying your tutorials so much!!!

these lectures are made with love

I have resolved the issue. I think, you have taught so many techniques and I applied and resolved the issue. Thank you

I'm using these working with my first arduino project and they work pretty good. Next im gonna try the HY-SRF05 Ultrasonic Sensor which is supposedly superior in terms of reliability. We'll see how it goes. Love your videos. Your boomer energy has me in awe.

Crystal clear explanation as always. Big thumbs up👍👍👍

I found the slope after fitting a straight line in MATLAB. The slope equals 0.0181 cm/us which means that the distance traveled in 1 micro second equals 0.0181cm. Thank you, you are a great instructor

Enjoyable tutorial and I'm slowly getting there, at last!!! Slope = 0.007 I intend to stay with it to the last, so please keep them coming. Many thanks

Heyy....i got 0.0075..almost close

Thanks for making these classes!!!

slope = 344 m/s or 155 cm/450us if we divide the time by 2 due to the bidirectional travel time. Thanks Paul. Another great session!

This is a great job for not the Serial Monitor, but the Serial PLOTTER. it gives you a good graph of readings, you can follow the shape, instead of trying to catch numbers scrolling past.

thankyou Paul, please keep these videos coming.

Awesome Lesson. Very detailed and the story line helps a 4th grader like me hooked

Thankyou so much sir Paul for teaching us this lesson, I now can have sensor to detect altitude from the ground for my drone.

Northern hemisphere (germany) Slope in cm. m=12,7cm/700ms Was able to calculate it the right way and display distance in cm on the serial monitor. Thanks to the fact that you have been repeating this kinda calculations over all your previous lessons and i can asure you, i aint´t a math pro. Thanks a lot

Slope is 0.0070 in/microsec. This is 2-way round trip speed. My measurement of the speed of sound becomes 2x583 feet/second = 1166 feet feet second. This was a good lab experiment. Thanks Paul. Keep up the most excellent work.

I just appriciate your style of mistakes. Yes, I yell out when I see your mistakes, but I make mistakes also. So then I have to trouble shoot one line at a time. It is comforting to know how to handle errors.

I got the slope as 0.193.. An absolutely perfect and clear explanation...

thankyou Paul, please keep these videos coming. yes I agree a Scope is a great tool to have

With my previous message being said, I'm finally getting a reading from my Ultrasonic sensor!! Thanks for another great video Paul! I'm going to run through all of these series in due time! Maybe sometime in the future I'll acquire enough skill to start building some awesome, useful, real-world projects. Hopefully some day I'll get hired somewhere where I can use the programming and electronics experience I will have attained to build some neat systems, because this is so enjoyable and fascinating to me!! 🤞

Thank you for your efforts ..I love watch your videos

the slope i got was 0.0075 Inches per Microseconds😁😁, and the slope means Speed. Mr Paul you make Math and Physics look exciting. WE NEED MORE TEACHERS LIKE YOU!! and i'm in the eastern hemisphere 😊

Hi Paul, The slope that I worked out was 0.00679 inches per microsecond. It looks about right compared to some other comments. Proper science experiment. Love it... :-)

Thank you so much Paul. I got y= 0.006m + 0.497. Outputting distance to my LCD display.

Wow, I got to play with my cheap usb hantek scope and got some nice square waves on it. Enjoyed the homework. My slope came in at .064 inch/microsecond, which will give the speed of sound there and back.

The slope of graph Distance vs Time gives you the Velocity. If we divide the time by 2 we can obtain the time it takes the sound to travel one way. Then we can take the integral over time of that new graph to obtain the distance!!!! This is AWESOME!!

You know, you've just made me understand how I could use an Arduino to know when the dog wants to come back inside.

I'm 12 years old and me and my dad are so happy that we are learning this, and this helps me become smarter......?!

I disagree, I think it is bringing the smartness that was already there before an outlet to show itself.

The slope according to my readings is 50. And so my formula to calculate distance becomes; Distance=PingTravelTime/50 And then I verified my distance using a ruler and VOILA! It's all correct. Thank you for the lesson SirJi.

I got a slope of about 0.006833 inches per microsecond. I think this is half the speed of sound because the sound has to travel there and back. I'm really loving these tutorials. Thanks Paul!

Paul, if people hate you due to your content and making them think then they really aren't trying to be an engineer.

who make unlike ? I am sure they are abnormal humans. the way you explained is perfect. you are the best teacher I have ever met. thank you sir.

Using the metric system, I got a slope of 0.018 cm/uSec. If I do the math, my estimate of the speed of sound came out to 357 m/sec versus the actual value of 343 m/sec. Not too shabby. FYI ... I got a slope of 0.007 inches/uSec. But I measured using cm, so I just did the conversion here to share my value in inches/uSec. Great lesson!

wow, thank you so much for this video, keep them comin'!

Thanks a lot Paul! The eqution I got by linear interpolation is 0.017x + 0.288 ( cm). So the slope would be 0.017.

Slope (metrical) 0.1648 => slope for one way distance 0.3296 => speed of sound 329.6 m/sec = an AHA moment for me, thank you Paul!

I programmed it to measure the distance: distanceIN=(1./148.)*pingTravelTime; //in inches distanceCM=(1./59.)*pingTravelTime; //in cms Great lesson, thank you for this excellent series.

Hello paul. i like your lessons..every one of them...I think this sensor is most sencitive in about 4"

After doubling the distance (away and back) and converting to SI base units, I get a gradient (slope) of 355 m/s (we dont use inch in germany). So roughly the speed of sound. I like your way of teaching, a nice experiment. Thank you

Hi Paul tanks for all these math homework love them! My slope of the line is 0.0166 here from South Africa. Tanks Paul and have a great day!

Hi, I'm way behind everyone else watching these videos, so you probably won't even read this but I am working my through them and learning a lot. I have previously used the HC-SR04, following an exercise provided by Elegoo. Other than how to wire it up and take a reading, it taught me absolutely nothing. Once again, you have provided a clear explanation of what's going on. Did the homework here in the UK and got a slope of 0.006557143, which, allowing for some pretty inacurate measurements, is roughly half the speed of sound.

Slope= 0,0175 for sm Thanky for tutorial. You are the best arduino teacher.

Thank you for your kindness Mr Paul..🙏🙏

I think the slope here in South Australia is 4.76 ms/mm (?) cant wait to watch the next video to find out if it is within ballpark. Thanks PM, you rock!

great video again! you should make a tutorial, about this sensor, using a minibot with collision avoidance . I've been researching that for sometime now, and all info out there, is just useless. only your tutorials are good to learn something. thanks in advanced.

Awesome! It's fun!! I got slope value as 0.0059. so it is 0.0059 inches / microseconds (speed of pulse) . Thank you Sir ❤️

Slope of the best fit line = 0.0061 inches/microS = 508.33 ft/s. We are measuring outgoing distance but measuring outgoing + incoming ping travel time. So, the slope is the half of the velocity of ultrasound. Velocity of ultrasonic sound in this experiment is 2*508.33ft/s = 1016.67 ft/s which is slightly less than the reported speed of 1120 ft/s, probably because of the measurement inaccuracy. Still it is quite impressive. Thanks for the great lessons again.

Peru present Paul! My slope of the line was: 0.016 [cm / μs] Please keep doing videos I enjoy them a lot. If you could make another course about python and Arduino (updated) would be great. All the best! 🇵🇪💪

Hey Paul, Thanks for these! Going through them a couple years after you put them out! But mu slope for my line was 0.007142 in/mcs.

great video

Hi, Paul, I incorporated this project into the DHT11/LCD/9vPower project, as I figured we'd eventually want to hook it up to the LCD and make it portable. I also couldn't help but calculate off the know speed of sound, rather than observed values, so 1125 ft/sec=13500 inches/sec = .0135 inches/microsec. So, after multiplying the microseconds by .0135, I then divided by 2 to compensate for out-and-back travel distance. Interestingly enough, that .0135/2 comes very close to the .007 range that many people reported... .00675 to be exact. Do I get a fail for using the speed of sound, or a star? My LCD displays microseconds on the top line and inches on line two. Walking around the house, it seems pretty accurate, but I don't know the limits of distance it can measure, as when I point down a long hall, the distance is under-reported. maybe it is bouncing off doorknobs or other closer objects. Anyway, another fascinating lesson and exercise... and I loved incorporating it right in with the previous projects (using the Nano and the jumbo breadboard). Thanks, as always.

From Montreal, Canada my calculation for the slope is 0.0067 and the values for time and twicie the distance (ping must come back) seem to represent the speed of sound.

I did it Mr.McWhorter, I got a slope of (15-2)/(868-147)=13/721 I'm using cm and microseconds, Hello from Russia~!

Hahaha I like that that don’t let the smoke out comparative lol. Reminds me of my transmission repair instructors examples lol.

Thanks Paul.

hi sir, i went through your tutorial and thats great.. i would be happy to know if there are any ways to calculate output of sensor in terms of voltage ??

The slope of the line that I found was 16/28 or .679 in decimal. For me the meaning of the line represents the ability of the sonic sensor to calculate the distance from itself to any object it is aimed at.

I love your joke about the smoke "these chips don't work without their smoke" 😄

It works. My distance =( pingTravel * 0.0069 )+0.134; I added an LED to fire off every time it sends a pulse, delay increased a bit, I also added an if statement that prints out "TOO CLOSE, BACK OFF!" when the distance

You made my day! :)

I came up with answers that seem to be close to others. My slope was m=4.437/700 = .00634. Using the point slope value formula that you taught us earlier I came up with a Point Slope Value of y = (4.437/700)(P.T.T) - 1.688, which should give us a "Y" value of distance at any pingTravelTime that is generated by the sensor. (I hope).

Hey Paul thank you for the great video once again, i hope you are doing well ! I was wandering if you know the Cypress PSoc, and if you might be willing to do some videos on it, from what i understand its like an Arduino but with built in components that can be activated with code, is that correct?

Getting a slope that approximates to the speed of sound in inches per microseconds divided by 2 - because it has to transmit to target and back. Found it hard to get exact measurements.

Hello Paul . I got slope for my case as 0.008 and I think it represents speed of sound

Thank you for your great video lessons...i have question please: you connected the sensor to the lower ground connection , so the upper ground connection is not necessary anymore , right ?

i found my slope (m) to be 0,006 (inch/uS). It's quite hard to get consistent readings from the sensor and its often off by +-100uSeconds. Since the signal travels to the object and back we need to calculate with half the travel time : slope would then be 12 inch/micro second. Close enough to the 13,5 inch per microSecond which is the speed of sound. Great lesson! and much better than the ELEGO tutorial which don't really explain anything.

Well, my slope calculated to 0.0064 inches/mS And what does it all mean, I think we are measuring the speed of sound here ?

I see there are different versions of the Nano; which should I buy to follow your EXCELLENT video series?

i got a slope of 6.78 x 10neg3 per microSecond or 6.78 inches per milliSecond. it means that it takes one millisecond for the ping to travel to the object and back so the ping is actually travelling double the distance or 13.57 inches in one milliseconcd. Double checking with the speed of sound at 1100ft/sec gives 13,200 inches per second or 13.2 inches per millisecond. I hail from Bay Area, California. Happy Holidays.

Greetings from Brazil! My slope was 0.0175, measuring in centimeters.

It is an irreversible process.

paul is it compulsory to keep the trig and echo pins as digital becuse i kept them at analog and it shows one

first one to comment on this video , love ur videos , the way u teach its cool , u explain each step and why these steps , , I didn't reach this video yet im still in video 39 , but i will catch u , ,,great job

Can I test echo overlaping using any ultrasonic sensor and esp32? I mean can I check if part the signal bounce back from the surface of a hollow object and other part go through the object and bounce back from the other surface? I need to measure thickness of a pipe.

Looking forwards to the next lesson, i have troubles thit this slope thing. But (pingTravelTime/2) * 0.0343 (speed of sound in cm) works for me.

Do you have an Amazon aff link to an oscilloscope that you'd recommend?

Maybe you cover this in another video, but what should I look for when buying an oscilloscope? Do you have one you'd recommend?

I have intuitively switched it over to [m/s], and I got a reading of 346 m/s, which is really not bad. 😊 Of course I also first made the mistake of not realizing that I need to use twice the distance, but I am proud to say that I caught my mistake. 🎉

Hey Paul. Love your videos mate. I have learned a great deal. Unfortunately, I'm in Australia, so for the coffee, it's a Farmer's Union Iced Coffee or it's nothing (refer to the TV adverts...you'll get it.) However I digress. I have a pair of HY-SRF05 u.s. sensors which can use the ping and echo independently. My aim is to get one to sing out to the other, sort of "Marko!... Polo!" style, then serialPrint what the receiving one is hearing. Any suggestions would be much appreciated. Thanks, Billy.

As clean as you are with cables I was shocked you had the USB issue. haha Had sprinkle salt over the wound on that one.
