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 RUclips. 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.
The majority of educational content is capable of replacing the universities. Hell some places flat out show you youtube videos as part of the class. Only difference is you're paying for it :)
I was literally just thinking, “this guy gets it, he’s not talking like i already know what he’s saying”. This is a huge problem when it comes to more advanced stuff. The youtubers always over-estimate how smart i am😂
@@AlvaroLuizTrentini his tutorials are horrible and leave ouit many critical steps, there is not even any servo category in y IDE under examples at all he also forgot to tell yout o set the board in board manager and the comport first
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 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!
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.
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.
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.
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.
There is a difference. The servo would move full speed from one position to another. with the sweep it moves slower which was intended for showcase reasons.
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.
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.
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 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.
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 :)
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
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!
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.
One thing : Arduino Nano and most of the new Arduinos can handle 12 bits analog inputs, but their default setup is 10 bits for obvious compatibility reasons. So if you want to keep the input on 12 bits resolution, the same as the output board resolution, just add the "analogReadResolution(12)" command in your setup and you can remove the map calculation. The R4 and Mega can even read a 14bit resolution.
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
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 RUclips 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 :)
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. :-)
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👏
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!
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!!!
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.
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.
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!
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.
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.
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!@
I am a beginner, but I would like to disagree with the explanation at minute 20:40: int val isn't what we read from the pot. At that moment into the programming it's just setting up an integer which could be for anything. A few lines later we actually declare it to be as what was read from the potpin. Please correct me if I am wrong. I think this "splitting hairs" explanation is important for beginners. Thanks for your video
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
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.
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! :)
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.
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?
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.
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!
Cool video thank you. I would love a short video of your workbench/shop. It look so organized and neat. If you could tell us how you made it, what you've built into it (I see a really convenient power and connection panel) and the rest. Thanks.
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.
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. :)
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.
Very nice refresher. Going to make some automated blast gates for dust exhaust system. Shop bought ones are $199 each. I have most of the parts laying around and getting a laser cutter anyway so... challenge accepted!
for my exosuit I wanted an easy to control piston, and I think a servo can be combined with a threaded shaft to make a nice piston! so I will use a continuous rotation servo and hook it up to a arduino to exten/retract the piston!
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
You're videos are really good, in my opinion your channel is one of the best when it comes to electronics. Thank you! But I would like to give a note to something: torque is defined by the (force applied) times (the distance of the point where the force was applied and the rotation axis), when the angle between then is 90°. In the servo specifications part of the video, you said that it is measured in terms of kg-cm, but I think it would be more precise if you use kgf-cm, which is a unit of force and distance.
H'actually, Torque (t) is the Cross Product of the vectors: Force (F) and Distance (r) where t=Fxr, x being the Cross product operator, and t is measured in Newton-metres!
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.

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
Great explanation, with practicals
Incredible servo introduction video. Thankyou so much! Subscribed!
You're videos are really good, in my opinion your channel is one of the best when it comes to electronics. Thank you!
But I would like to give a note to something: torque is defined by the (force applied) times (the distance of the point where the force was applied and the rotation axis), when the angle between then is 90°. In the servo specifications part of the video, you said that it is measured in terms of kg-cm, but I think it would be more precise if you use kgf-cm, which is a unit of force and distance.
H'actually, Torque (t) is the Cross Product of the vectors: Force (F) and Distance (r) where t=Fxr, x being the Cross product operator, and t is measured in Newton-metres!
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
You have described them very well !
Hi Bill,
Excellent! Good general information for every E.E.
