Using Servo Motors with Arduino

[@normanhall5902]

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 KZbin. 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.

[@asdf0019]

Very useful. Thank you!

I totally agree!

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😂

[@The_Daddy_2012]

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 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.

[@olavodias]

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.

[@larrybud]

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.

[@noobdernoobder6707]

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.

[@roberthatfield8966]

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.

[@schnasndasn1504]

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.

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.

[@cliftonsmith8269]

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

[@mrt4091]

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 KZbin 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)

[@mukageegee]

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

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

[@acehaag]

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.

[@parthasengupta3904]

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.

[@Love2Destroy]

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

[@mcviggles2784]

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!

[@liolikbolek5780]

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

[@ericseidel4940]

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.

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 :)

[@greggtracton2588]

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.

[@AnakKosanLife]

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

[@icm3523]

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.

[@AkashJadhavIT]

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

[@zackkhan1199]

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.

[@theabstract100]

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!

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!@

[@philipebandeira9292]

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.

[@ChuffingNorah]

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!

[@enriquemorales8419]

[@JSCB-365]

This was a great Video and it has helped me understand each topic covered in this video. I have a project where I intend to run a large 80x100 Brushless Motor with a 300A ESC I currently use a servo tester but I find the knob is touchy. And lacks finer control. I would like to set up an Arduino to control it in forward direction only. Possibly incorporate serial feedback for RPM as I know the motor has sensor wires built in. Ultimately I'd like to have the CNC controller communicate with the Arduino to turn the motor on and off or to select the RPM. At this point I'm fine with setting up preselected RPM settings. Serial connected to the Arduino or through buttons or switches.

[@JSCB-365]

So what I'm saying is if love to see a video covering the topic of controlling a brushless ESC with an Arduino, with several possible setups. Explained by You! Some of the videos I've watched leave me scratching my head. ps: I'm currently running this Monster brushless motor on a Sherline CNC mill.

[@omkar187]

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

[@colintelfer2756]

Well this has enlightened me on the arduino programming with regard to the effect of pulsewidths and how the calculations are carried out etc. Would you have anything on sensor shields with the arduino?

[@Gallardo6669]

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

[@dansquires2713]

[@PatnaikUC]

The tiny little onboard SMD P channel MOSFET ( working as blocking reverse battery supply) of PCA 9685 which is in series from the 2 pin servo supply screw terminal feeds the servo pins V+. Thus if 16 servos operate at a time with some little load from the V+ the tiny little MOSFET on the board simply smokes as the current goes well above its handling capacity. One solution is to bypass the built-in MOSFET but then the strong back emf from servos retrigger the PCA 9685. What is the solution?
