I’am 74 & can listen & learn from you 24 hrs a day & learn & it sinks in i was a commercial mechanical engineer for year , never got involved with electronics which is my hobby know some people you listen to it goes right over your head. You are good thank you Norman.

This was unlike anything I've seen on KZfaq. Came for a refresher on arduino servo control and got SO much more! Content like this has the potential to replace the university system. Will be watching more of your videos and encouraging others to watch. Well done sir.

This guy makes the most comprehensive tutorial ever! He even explained each line of the code! I have learned a lot, thank you so much!

I haven't seen the full video yet, but I really appreciate what you're doing. Your style of teaching is very clear, calm and easy to follow.

By far one of the very best electronics teachers out there. Clear and concise without any ‘greater than though’ attitude. I beg anyone interested in electronics to subscribe and support this incredible resource.

I don’t normally comment on videos but this time I’ll make an exception. Your presentation style is spot on. Clear and calm. You also don’t do what every other educational video does and expect the viewer to know everything. Usually watching an educational video just starts a long process of watching other videos to understand what is happening in the original. Thank you very much!

I have always believed that young people are the best to explain sth to me till I saw your channel & realized why experience really matters... You are the best ever...

I am 90% into a DIY Eggbot. The servo that lifts the pen is kicking my butt. The video is comprehensive and I have to say the graphics are very polished. Thank you for sharing your knowledge. Thank the people that help you produce this content as well.

Another example of an absolutely brilliant and concise presentation of exactly the information people need to understand the topic. I appreciate not only the obvious work you put in to researching the broad variety of possible applications, but also the visual aid presentation and video editing necessary to bring it all together. Keep this up and your library of videos is destined to become the be-all and end-all of youtube workshop references.

As a beginner, I can say this is the best channel which offers such clearity for doing things

At 40:58 you say "I hope you learned something about server motors". You gotta be kidding, I've learned A LOT, I mean, really, A LOT. I'm very thankful for your video. You are the best.

Thank you so much, not just for this but for all the videos you made. Every time I start working on a project I start with some crappy 3 minute video an get stuck at some point. Then I watch one of your videos and the problems go away because your videos include all the necessary informations. Happy new year! Keep up the excellent work! Greetings from Germany :)

Nice introduction. For others, in his initial code at 17:00, there's no need to "sweep" each degree. You could simply write 0 to the servo, wait a bit, then write 180, wait a bit, and loop back to 0. 3 or 4 lines of code.

i was searching for a channel like this where arduino is taught comprehensively...found it 2 years late but glad i found it ......will surely learn a lot from you sir.

I started watching this video at two times speed but then I needed to slow it down. But after listening at two times speed I can now only tolerate watching this video at 1.5 speed. Great video very informative and through!

This is really high quality stuff! I really enjoy watching these videos. I liked seeing how you used the oscilloscope to show PMW. I "got it" without that, but it really hammered home what is happening there.

I´m a beginner and I´ll create an "Useless Box". Your videos help me to do it - and I´m so thankful that I subscribed your channel.

I have not seen such a comprehensive , data rich, lucid and informative video tutorial before. I would like to thank you very much for your effort from the bottom of my heart. At the end of the tutorial you feel amazed at what you have learnt from scratch. I would like to know the details about constructing the robotic arm that you used to demonstrate the working of PCA9685. I am an Electrical Engineer and have interest in Arduino Projects, which i keep doing for my kids school projects. Thank you once again.

Great video, very clear. Thank you very much for speaking slowly and clearly, it is really appreciated for not native English speakers.

I love the calm approach too. Some people suffer from a slow curve. The speed of presentation is just right.

Thanks sir for another great, extremely clear and friendly lesson/demo on servo motors for Arduino. You are the best!

Great presentation! I'm a retired EE 10 years of Arduino experience. I've seen these RC type servos before but never used one. My experince have been with larger DC motors. I'm currently working on an Arduino based cuckoo clock, these will work great thanks.

greetings from morocco sir.....im not an engineering student and still can understund you well...thanks to your exeptional style of teaching

I honestly appreciate your work in these videos. This is the best channel in it's category I've ever come across!

I am very grateful to you for your lessons, especially for your excellent clear and distinct English

First half was pretty basic and explained in depth, second half was a big step up, really liked it :)

One of the best teachers on youtube!Hands down!

ड्रोनेबोट workshop site videos are very nice, explains in a most systematic way..

Very thorough. I really appreciate you explaining everything in the code instead of breezing over it like most do.

As a beginner I learnt a lot from ur teaching and I am planing to do a project on 4 legged mini robot so plss do come up with more videos or tutorials so that beginners can learn easily...... Very good teaching👏

in a pinch you can turn a standard 180 degree servo into a continuous 360. takes a few minutes just glue the potentiometer and remove any mechanical stops. there's some good KZfaq tutorials on it. really helped in my project. I needed to drive a gear system and 360 servos weren't compatible with the RC plane receiver I was using to control the servos. (9 gram micro servos)

I was not ready to try servo with PCA9685 (since datasheet says it is for LEDs) till i saw this, great tutorial. I am going to watch all of your videos now :)

Very informative and easy follow video. I'm starting to learn Arduino and build a small robotic arm with 4 servos and was unable to find out how to control servos before I came across your video. Thanks for sharing your knowledge, its great for my learning.

Thanks so much for this very very good tutorial. I knew nothing about how these servos worked and now I'm on my way to starting my first project with them. :-)

Do you have a background as a teacher? Your teaching style is absolutely fantastic.

Omg thank you I could not get the servos to work till I found you video. 10/10 Will subscribe.

Sir, you are the only person teaching at this level on the youtube that is easy to comprehend. Can you make a video about controlling servos on a pca9586 board using an arduino connected by bluetooth to a phone? I am about to build a robot head and have no idea of how I could use arduino to move it, so I really would appreciate your help. Thanks in advance.

I liked the video before watching it, I was waiting for your new videos, your channel is the best I ever seen, thank you so much :)

Thank you for this video! Very great explanations, easy easy to watch and understand!

I've watched several of your videos. Very easy to follow and good information for students of all ages and levels! Thanks for sharing!

DUDE YOU SOLVED A LOT OF PROBLE I GET DRING SERVOPROJECTS THANKS SIR REALLY

The best I’ve seen on arduino and servos

Incredible how helpful this video is. Needed a refresher on servos, building a remake of the the classic board game “Dark Tower” which featured a tower with an electronic spinning window

This tutorial about servomotor was the best that I've ever seen

Thank you so much for making this, this is exactly what a rusty beginner like me needs. Seriously, thank you

Using this video to help with a final year project in university. Thanks for taking the time to make this video very clear and concise, it has been a massive help! :)

excellent video! one thing I've never found on the internet is a tutorial explaining how to use a serial servo (eg. Feetech scs0009) with Arduino. This type of servo can report temperature and force levels back to the microcontroller and would be a good thing to have when designing robot arm grippers where you only want to apply a limited amount of force when gripping an object. If you ever have the chance to work out the Arduino integration, this would be a useful tutorial

Love the super light smirk he makes at 27:50 "..if you need to control more than 900 servo motors with an Arduino..." LOL 😂

Another excellent video. Once again I know have an idea for servo's and the courage to have a go! I have no idea how you do it but I learn more in 45 mins watching your video than I do with hours of researching myself. Keep up the good work! Right, now to subscribe to the newsletter.

Hi Bill, I've just got around to watching your Servo video - another educational great. Thank you so much for posting this. It will have saved me alone many days of frustrating research and messing about.

thank you for explaining servo motor I learned many things after watched this video

Thank you so much for your great video. Soon I will do it myself first and upon successful operation will teach the same to my students at the class. I am Harry from Mareeruk Chiangrai Primary School, Chiangrai Thailand. Wish you Good Luck sir.

Thank you very much for your video. Your teaching style is very easy to understand.

One of the best video lectures I have seen. The explanation is very clear and structured. The graphics part is very well done. Both the hardware part and the code part are explained very clearly. Thank you very much Sir!

Man this is what you call a class

Thanks very much for creating comprehensive high class tutorials.

I have recently discovered your channel. Absolutely brilliant! Very educational! You deserve a lot more subscribers. Cheers

Have not watched the full video as yet but its great so far, you teach clearly. Thank you sir for making these videos.. You have a new sub

The best electronics tutorial video I have seen. Keep up the good work.

Thanks a lot for the video. I am trying to build a remote device to control the amount of oxygen coming out of his tank (needs separate oxygen because of health issues). It is a simple rotating lever, which should be changed with the servo motor to a certain postion via bluetooth with his mobile phone, since it can be frustrating if you sit 10m away from the tank but you need more oxygen. Did not quite figured it out, put this video helped a lot!

You are a great methodic teacher. I a m so so happy. God bless you

Great video! Answered every question I had and several I didn't know I needed. Appreciate it!

Just absolutely awesome,... I appreciate the simplicity and directness....so eell done

You rule! Long live this workshop!!!

I love you video is because is very explanatory and at a speed I like. My goal is to create a Spiderbot with 8 legs. And you gave me the answer. I will keep studying with your others video until I reach the knowledge to complete my electronic project. Thank you very much!!!

This is a masterpiece of education! Fantastic work demystifying servo motors!!!! Thank you so much!!!

Thank you , you provide great information clearly and simple to understand

Incredible servo introduction video. Thankyou so much! Subscribed!

Another great tutorial Bill! You certainly have a great aptitude for teaching.

Great Video, But a little tad-bit to add. When using the Servo Library included into the IDE, a PWM pin is not required to operate the servo. The Servo library simulates a PWM signal using the onboard timers on the arduino. I run 3 servos from the A0-A2 pins on a homemade robot to keep all my valuable digital pins available. Cheers!

Super helpful video! A small correction though: Torque is not measured in the units of kg-cm (or kg-length). It is measured in Newton-meters or Newton-[length]. Kilograms are not a unit of weight but a unit of mass, while Newtons are the unit of weight in the metric system.

I found you a few months ago and absolutely love your channel! Thank you for putting all the time and energy into your videos, I know it is time consuming. I am looking forward to putting all this knowledge into use sometime soon! Thanks again and please keep up the most excellent work! Are you an instructor by chance?

Thank you for posting these knowledge videos! Hobbying into electronics in my spare time outside of my busy work life.

Thank you for the positive message that you transmit with your videos along!

Your videos are fantastic. Extremely well explained and demonstrated. You should be a teacher. This will help me in my Lost In Space Robot build I am trying to control with Arduino.

I was wondering how people controlled more then a few servos from and Arduino. Thank you as always for your classes. If I were still an instructor, your classes would be mandatory watching for my class. :)

This is excellent, jumping in for hobby and work and loving this already!

Subscribed. One of the clearest and most thorough presentations!

This video is just what I needed to give me a head start on my DCS A10 sim pit. I am using servo motors to replicated gauge movements in the software and there are over 30 instruments in total. It would have been a nightmare to individually wire each and every servo . Now I can install the servo board on the dash and only have to wire the communication lines to it. Thanks so much!@

Thank you so much for your clear and relaxed explanations, now i really start to understand how it all works,

That filled some 'holes' in my understanding of servo datasheets etc. Much thanks

Awesome presentation and describes everything to the last detail in a very pleasant way to understand, GREAT JOB

Your the daddy! I've learnt so much- thanks.

Excellent presentation...... So calmly provide the clarity, great.

Very informative. Enjoyed and gained a lot from that, have kits and need to make time to play. Thank you for your efforts.

Thank you very much for this video. You are a very good teacher. Your explanations are clear and concise, you take us step by step, explaining as you go both verbally and visually. I knew nothing about servos beforehand, except for the word. Now I have a head full of ideas. It is the same with your other videos. Thumbs up (using my native liveware servo) and subscribed. I enjoyed your dry joke at 27:44

thank you sir you clear my concepts about servo and code of arduino really appreciate what you are doing for us love it i am student of university and this video your teaching style is great thanks again.

You have described them very well !

Thank you very much. This really helps me fully understand servos

Hi your are super good teacher.Keep it up

Your videos are very very well done. I learn so much every time.

I truly wish you had spent a tiny bit more on the PCA9685, perhaps a sweep for the servos using the map function. People used to controlling servos using degrees are completely lost, it maybe it's just me. Thank you for these videos.

Very nice video. Some improvements: - watch the camera when you frame a shot; there were a few shots where you either block what we need to see or else the important parts are out of view. - You speak of scaling up using the PCA9685 to multiple servo motors but don't talk about the scalability of the I2C serial communication, which I'd like to know if I'm going to create a multiple servo design. I'd want to know if I set an angle (pulse width, actually), is the library smart enough to send the signal only once. - In the last demo, I wanted you to manipulate all 4 potentiometers at once to show that there's no lag and that they don't get confused. - I want to see safer code that imposes limits on the pulse_width calculation to make sure that they are in range and won't hurt the hardware. And also options on what the software should likely do if the limits are exceeded, such as clamp it, light up an error LED, or ignore the value. - Please explain what "start()" does, above and beyond what the object's construction does. It's doesn't seem necessary to the design, that is, you didn't justify it in the video. - "controlIn" and "motorOut" variables should perhaps be named "controlInPin" and "motorOutPin". And what does the 100000 factor do in the equation? - where are good sources for servo power if I don't have power on my bench? (Or, like most hobbyists, don't even have a bench?) You don't have to explain that fully but a reference to another video would go a long way to reducing my learning curve.

brilliant video! thank you for the clear and calm workthrough of this

Thanks you! Video was very educational. I like you style and your speed. Easy to follow.

Nice video, thank you for taking the time to put together a complete informative video. I learned lots!

As always very educative and very professional video ! Thank you so much for sharing your knowledge. Regards, RJM

Great watched all the video very informative and easy to understand, Thanks

this the most detailed Servo motor video out there, which also explains what each pin to beginners like me. thank you so much. 1. would it possible for you to make a video of how to control multiple servos at once rather than running one at a time using PCA9685? 2. Also how to mod this same servo for 360-degree rotation so we can control using PCA9685

Just discovered your channel. Very helpful. Thanks!
