Great video. And because you do not use a library it gives more details on the inner working of the sensors.
Isn't wire a library?
Richard do you want to write high and low for every single bit?
Sir...your tutorials are also nice!!
Favourite man with Swiss accent :)
Andreas Hi!
This code is simple and clean.
I learned to program by studying pinball machine firmware at a time when the engineers were forced to use assembler language for 8 bit processors. The Williams pinballs were using the MC6800 first, then the MC6809.
When I started to use C language, I found natural to check that the compiler generate the same assembler code as the hand coded version that I knew for years.
The code to read two I2C bytes and make it appear as a single 16 bit integer would be:
X0 = Wire.read(); //get D7-D0, the 8 least significant bits
X1 = Wire.read(); //get D15-D8, the 8 most significant bits
X_out = (X1
Thank you sir!
I almost lost hope while searching for the videos that explain the basics of gyros..but then I came across your video. great explanation, i must say. First, the basic working and then explaining the code (rather than using the libraries like others).
Thank you
Thank you! I watched 5 videos in an attempt to understand the mechanisms you illustrated more clearly in under 10 seconds.
Best tutorial so far with excellent graphic. I will now check on your vebsite.

One quality engineer.
this is what i call a perfect explanation suitable even for some of us who are slow to learn. like the illustrations too.
This is an excellent tutorial - concise and to the point. Thanks for putting this together
I would pay a lot of money for one of those things. Just beyond me to set it up. Loved it.
Very useful documentary. I use this to make my training materials and aware knowledge of Mechatronics/Innovation students etc.
Great video. I guessed it was a mechanical system at that level, but seen how it worked add another level of amazement for me. Engineering is awesome .
😃😃😃
Glad you enjoyed it!
GREATLY impressive…
We WANT that technology !
I can't wait to build mine. That's sick
Very well explained, the video on physical functioning of accelerometer helps a lot!
Great visuals! This video was informative. So many people use the term accelerometer and gyroscope interchangeably, but they are very different sensors.
Thank you, now i know why my drone takes off sideways lol
ok this is awesome tutorial .. and the explanation on the website is fantastic, simple, and clear ... and as Andreas said, you're not using libraries so you are showing how things are going on in depth .... BUT ..
where is the way you are integrating both Gyro and Accelerometer to get better performance ? I didn't see it on the website ...
Plz guide me for this ...
brief and useful.
nice accent...
Great information. As always I enjoyed the video. Please, however, speak a little bit more slowly. It is hard to digest all of the information so quickly. Keep up the good work.
I used ARDUINO MMA8451 accelerometer, it is great!
Your tutorials are so cool and detailed. thank for uploading.
Дружище, ты русскоговорящий по любому.
Big like and many thanks
i like writing codes with out using libraries thank you
Sir, thank you for your hard work. it was really help full. thank you again.
Great Job, really clear explanation and nice animation!
Thanks!
Interestingly enough I'm pretty sure the HMC5883L is a magneto-resistive sensor. Kinda cool to find this video right now as I'm working on using the gy-88 board for a robot.
thank you so much professor. this video was extremely useful for my project. cheers!!!!!!!!
Hence the old saying, "Drifty as a ten cent gyro."
"وما اوتيتم من العلم إلا قليلا" صدق الله العظيم
Thanks a lot for this demonstration.
It's simply wow how these chips work
Really good video, It helped me a lot ! But It would be perfect with a tutoriel (or a presentation) of the 3D exemple, because I would really like do It !
Science is magic!
Thank you a lot for the information and explanation
sir all videos are good ...especially i like your logo of channel ..
Great video, BTW the L3G4200D is obsolete so you need to select different chip for new designs
great video, simple and very useful.
Excellent ! Thank you
One of the Most Useful and Informative Channels Ever :D Thanks A Lot Eng. Dejan ,,,,, And also thanks for giving your Source Codes because that also help a Lot :) Thaaaaaaaaaaanks
great video, to the point
This was a really excellent and informative video.
thank you
Thank you very much Dejan Nedelkovski,
but sometimes you make mistakes in connecting
the sensors with arduino, try to avoid it
Very nicely explained...thank you!!!
this might be one of my first subscription and thumbs-up, great vid. do you make videos about your processing sketches? for the gyro and accelerometer
Thanks for the video... I wanted an overall view and animated construction,working of mems gyroscope..
Great Tutorial ....please add the source code for control with filter an 3D object to your web site! Thank you Dejan!
Wondering why you divide by 256 instead of shifting (so, SO much faster). Instead of Xa = X_out/256; Xa = X_out >> 8; This might make up for the lag of the cube that you see. Just my humble opinion... GREAT video though!!!
excellent description sir. sir the values obtained from mpu6050 is not stable sir how can i get the value which do not changes at the same position. so than i could use it in my project.
Thanks Dejan Nedelkovski, it was a great video. I got many thing to learn from your video but do you have any video regarding how to make Gyroscopes sensor or something similar?
Very useful, thank you.
Thank you so much! Nice work!👏
Hello, nice video !! Quick question: how would the gyroscope work if it was rotated about a shifted axis ? (ie, the axis of rotation does not go through the gyroscope)
My experience with magnetometers is, that they are pretty unreliable. Can't seem to get valid readings near motors or large metal objects.Any thoughts on improving that? Also it would be nice to have a more in dept video, about correcting the gyro drift.
good lord, you're a genius!
hey,dejan,i guess there is connection mistake between arduino and GY80 at 3:26 of your video, you connected the GND of arduino to the Vcc pin of gy80, but i think the Vcc pin should connect to 5v of arduino
Wow that's how my quad flies!
Very nice sir...
So it should be possible to create a gyroscope that doesn't drift by using the combined input of the gyro, accelerometer and magnetometer, at least if you aren't on any of the poles, right?
I am a PLS and have long wanted to make an inertial device for land surveying. However the device would need to be about 50 times more accurate than what is currently available using these MEMS. It seems that having the sensor be a mass suspended on springs is the limiting factor, and that a ring laser would be much more accurate and lass prone to drift errors over time.
Hello just a question can tou put a gyroscope in your device? Like replacing the hardware?
hey man, great vid, did you made the application yourself?
Great video
Can the combined code from accelerometer and gyroscope be found somewhere? I can only find the accelerometer and gyroscope code separated.
Thanks for this awesome informative video ;
Please, I want The State Space representation of gyro mems for builder filter kalman
Good introductory tutorial.
Any resource on how to implement the same using a PIC microcontroller instead of arduino?
wonderful vedio! how did you make, which software?
gosh it is so cool,,, thanks for this video
You're welcome 😊
super helpful, thanks!
Nice video thanks
Superb video!
This video is cool, just I have some questions please:
To communicate with the sensor(accelerometer for ex) we need to know the who am I register and the read operations? Is it right?
Then to receive data I can’t really understand what to use
Someone can help?
EXCELLENT!! thanks a lot!
Hi..Can we connect 2 or more MPU6050 to single arduino??If yes, how to distinguish them from each other?How to use different addresses while programming?Please respond..
Tushar Tembhare you can only connect 2 at the same time to an arduino , and to diference you have to declare the address of each one
Thank you for the explanation. The acceleration on the surface of the earth is 9,8 m/s2. This could be the acceleration of the crust of the earth upwards OR the fall of an object downwards. If you throw the device in the air and you read the acceleration in free-fall, you will see NO ACCELERATION. If you take it in your hand again (or put it on the table) with the upside up, you will read an upward acceleration of 9,8 m/s2. This means: the device is telling me, that the device (me, my hand, the table) is accelerated upwards. Does this mean that the earth-crust is pushing upwards causing an acceleration of 9,8 m/s2 upwards? Is there a way or reasoning to distinct between these two possibilities?
Hi! What kind of filter you used? I mean for the application of the gyroscope you said a complementary filter, do you have some tutorial about it? Thanks!
How can I combine the gyro and accelerometer data? Is it on the code on the website somewhere?
Awesome explanation for everything! I followed you and I will always be following you!
But I have one question: Did we use any kind of filter to reduce the noises? And if not, shouldn't we use one?
Thanks! Well I didn't use any filter but yeah to reduce the noise a some kind of filter is needed.
@@HowToMechatronics yesterday I did what you did exactly with the same code and the same hardware connections. The code worked. However, the values of Anglex, Angley, Anglez are decreasing equally from 0 till - infinity. Where do you think is the problem?
Congratulation my friend. Great explanation !!
+Dejan Nedelkovski Dejan I want to make a project using similar your radar project, for example If I put 25 T-Shirts on the table, and my "Radar" must To Read 25 around, if I take 1 T-Shirt, my system must count and showing 24. I guess that I need use RFID tag and antenna uhf rfid. Am I Right ? P.S.: Sorry my English
Ok. Thanks
Hi I have a doubt what happens to output of accelerometer when accelerometer is moved with same speed for some time will it be zeros or some constant km/s^2
Wow. First-rate tutorial!
Does the compass have to get calibrated after some time?
At 1:11 , why there is an angular rate? Where does it comes form?
Awesome job!
Good tutorial.
The variables angleX, angleY and angleZ aren't initialized in your code. So, for the first measurement, what values do these take?
Sir, I need to find altitude by using MPU 6050,so what will be it's code and any other sensor will use or not?
Wait. So the gyro points to an initial direction chosen (not true north) but also wanders due to the Earth's rotation 15⁰ per hour, so you canceled out the rotation of the Earth with the accelerometer?
Do you have the IDE for the 3D block rotating with the gyro as well? I could not find it on your website?
Loved your video btw. Thanks a lot for sharing.
Dejan Nedelkovski thanks so much! my project is due on April the 15th and would really appreciate it if you could release it before then. I understand you have your own timelines in mind. I have sent you an email @ your hotmail. Would it be possible for you to send me the program standalone via email? I would greatly appreciate it. Thank you so much for your responsiveness to the community you have built. It will certainly not go unoticed
another very clear video.
may i ask what software you use to make your slides
are you able to give me some guidance on a project i would like to make. i would like to be able to measure vibration x, y and z values in three areas within 400mm of each other and be able to record the data a export it into a spreadsheet. what sensors should i buy to be able to start this. this will be my first ever project
Thanks a lot
nice tutorial, i visited ur pg but did not found the processing example
can you upload it sir? I'd like to test mine if my module is working properly in 3D figure... :) Thanks in advance sir :3
this video should be recommended to flat earthers haha
Sir, I want to ask that how to measure speed of vehicles with XYZ values of accelerometer please tell me.
NICE VIDEO best explanation for advance data obtaining! Just a question, where Power_Register comes? Data sheet? what it means? thanks a lot!
nice video
please tell me what programs do you use to make these animations
This is fascinating thank you so interesting
Hello HTM, could please share the code to combine the accel and gyro sensor value for better result ?. thank you
how can I combine the data from the accelerometer, gyroscope and magnetometer to generate an accurate data
Great job ! thank you
thanks man really helpfull
I'm really lost between the three sensors! Are they similar or what?! Do they share similar functionality or they are completely different?
I learned some of the HMC5883L and got the atan2(x,y) to get the heading which is I guess in radian. So I got the 360 degrees heading, but what does the z-axis do?
And then what does the accelerometer has to offer other than the HMC5883L? And how's the gyroscope is different than the other two?
Interesting Video, What's the name of the Sound Track?
