36. Arduino for Production! Introduction and How to use Servos and Understanding Torque 

Hello Patrick, I don't how to start thanking you for all the efforts you have put into these series, I could not believe something so simply, high-quality and smooth to understand. I would like to thank you and I shake your hand. Thanks.

Jesus...you summed up in 10 minutes what my high school physics teacher took a semester to explain..I finally got it. Your info will def come in handy, thank you!

Great job. I learned in this weekend watching your videos, more that I learned in a month reading books about programming microcontrollers. This videos are perfect for a beginner. The only problem is that now I am addicted to this stuff. I NEED MORE TUTORIALS.

I did poorly in math in school. I learned about electronics and have always wanted to do animatronics but I didn't understand servos. I watched this and the PWM video. Thank you sir for explaining it so well and it makes sense, your a great instructor.

Quality production values! The speed up of the video in not-so-interesting places is a nice touch!

Excellent - clear, concise - no frills. I have shared your link with my group as I do work with servos but hate to discourage their uses with technicalities. Thanks for sharing, and good luck !

Thanks I really appreciate you pre-fast forwarding all the white space in this video. If you skip 1 minute of whitespace here that is almost a month of human time saved for 38k views of this video already

This is supremely interesting and well explained. This is what the internet is for!

A useful, practical video on servos- their construction, operation and the torque they produce.

Great editing! So many videos just play the 5 minutes it takes for the speaker to unscrew the device, you fast forward through it. Very considerate!

Mr Daniel, never got past high school math, never took physics or any math related subjects. Have seen this video before and it makes sense, thanks for putting these together. I am learning about servos to use in animatronic characters.

Absolutely brilliant! Thank you so much for this video. You managed to explain the torque issue in an easy to understand way... It finally all makes sense to me now... Cheers from Australia, Rolf

@phalegh You're welcome. This is also true for all of the force-length units, like lbs-ft, kg-cm, N-m, etc. The only difference is the magnitude. Enjoy and Merry Christmas.

immediately after you broke your sevors circuit board at 04:22 , I like your video for your ultimate sacrifice.

I watched Rick Lazzarini from Stan Winston school and servos are heavily used so this really helps!

Thank you so much for this wonderful comment. Comments like these really motivate me to keep going.

You've worked so much for these videos. Thank you for your efforts.

Stuff I sorta knew already, but now I'm able to explain it to others. Cudos! Excellent presentation & thanks for publishing it!

@axel1973w You are totally right. I forgot to mention the Newton Meter. But I like to think that I drive on the "other" side of the street. Haha! I will add some annotation on the video and add the information to the official page for this video. Merry Christmas

Great job on the tutorial. I still have some questions, but you answered everything that really needed an explanation. Thank you.

Excellent. I've always wondered what the heck oz/in meant but have had trouble finding a clear explanation. Thanks for making it so easy to understand.

Nice and clear. I'm a newbie and I understood almost everything I think. Thanks!

Best explanation of servos i have seen so far!

Thank you for your generosity! Good & helpful videos Patrick.

Thank you. I hope to be able to help myself and kids with your videos.

WHAT!?!? Your writing utensil has been a pencil all this time? My mind has officially been blown

Thank you for posting that video. I am starting from scratch

Hey Patrick! Your videos are really awesome and very intuitive! You should do a tutorial on interfacing GPS with MCU or wireless ICs to MCU if possible.

Thank you for making this video - I'm working on an animatronic dragon and this is helpful. Don't listen to the troll who commented on your speech - he must have OCD to be that frustrated by a simple pause in speech.

awesome videos! good explaining, video editing and camerawork! wrong measuring scale but what ever.. really logic explaining and easy to understand! :D

Thanks for breaking servo's in the name of sience ;) Merry christmas.

You're welcome.

Thanks so much ! During your videos, i could unterstand MC

You can watch the next videos on the playlist and it will show you this tutorial.

I agree, excellent videos. Very clearly explained. Thank you.

The application for that servo is more intended for linear motion, or other mechanical precise movement and positioning. I will get more into the details on this type in a future video.

@TheDragothica May the servo rest in peace!! Merry Christmas

@squiggyreck Thanks and you're welcome.

I need one of these for my prototyping

@julioza You're welcome.

awesome vid! 7 mark wicked upside down writing skills!!

Well done, that explains a lot...

I kept the broken servo as a memento! Thanks.

Thank you ! Its very informative.

Thanks farnoise

This is very helpful..thanks for posting it

Thanks!

Thanx a lot, very helpfull for me from Indonesia.

Nice video. I'm technician that haven't played with electronic since I'm too busy or worked out at the end of the day so I never get to play with these nice electronics. let me know what you have ready to play with so maybe I'll get some of it to start enjoying electronics again as I used to in the beginning. Thanks. Z.

i appreciate i got from you DEAR SIR

To find the gear ratio count the number of teeth on the respective wheels. Small may have say 12 teeth and large maybe 60. This would make a five to one gear ratio. (60 divided by 12 = 4).

Thenk you for the explain, really really useful

wow, your a very good teacher, thanks

Thanks

beautiful explanation...

Thx. Its easy to understand.

nice explanation

Thanks for the Lucid Explanation sir.

great video Thank you!

Great video! Very informative! :)

Well, I like pen and pencil, but I make a lot of mistakes, so I tend to lean towards using a pencil.

excellent .explanation

Thanks for the clear explanation. How do you do an auto stop circuit, for the motor to stop turning if jammed?

Thanks for you astounding explanation. Might I give you a suggestion though? You have an international audience, so why not provide simultaneous conversion to the International System? like saying 6 inches (15 cm), or 6 oz.in (42 mN.m). That would help a lot, because I lost sight of intuitive notions of size and speed in the middle of your video.

Well done mate

Neat video, Great Info. Thanks

Great explanation, also good to see it's possible for someone to bite their nails more than I do... aha

Hi Patrick, your video helped me understand this stuff a lot better. Any chance of going metric. :)

good stuff

@mughalles Thanks. What is MC?

Great tutorijal, thanks a lot! Could you tell me pls if I got it right: So the black wire carees the information about the position of the motor, so it is conected with the potentiometer? based on the position, we can calculate the current speed, and then the microcontroller (PWM) on the board will automatically calculate the accurate pwm duty cycle needed for getting the wanted speed? so from the automatic system controling point of view, the pwm is the regulator (controler), and the potentiometer the negative feedback?

Liked and subscribed.

cool video man

THANK YOU SIR GREAT EXPLANATION

great!

Do you know if there is any company that sell the servo driver boards? "I have a truck load of servos that the boards burned way back! and I have been saving them"Also it would be kind of nice to make large servos!!

@Patrick, Sorry I forgot mention my question, do you recommend any tutorial on how to control Servos through Microcontroller, (I am not talking about using sensors, more like manual controling, and signalling Servo)

i have a question regarding the use of servo mechanism for opening and closing of the control valves in a thermal power station,being a mechanical engineer my knowledge regarding instrumentation is pretty less so i would be thankful to you if you could help me out,..the control valves are basically used in the path of main steam piping and are controlled using hydraulic oil pressure which includes a servomotor mechanism..thanx

Using a receiver and a transmitter how can i set up servo #2 to rotate exactly like servo #1???? so that i can move a robotic arm say thats a few feet away from me? can you maybe make a video to show us how to do this? I want servo #2 to rotate the same amount when it receives the signal from servo #1

I'm alittle confused. I want to have a servo rotate 90 degrees when power is on, (12v) and stop at 90 degrees. When the power turns off, i would like the servo to move back to position 0. How can this be done? I would rather not have a controller box and code. I would also need to find a heat resistance set up.

this video was perfect except for the imperial units.

it is awesome to have this tutorial. Thanks!

My wife would like you to teach me how to make my fingers as fast as yours do when pulling the screws. Can you teach me?

Cool video, but cooler pencil. Where can I get that pencil? Thanks.

hi...excelent job.... wich is the value of the potenciometer?

niyamai

@mughalles Hahahaha!! I can't believe I missed that one!! MC=Microcontroller=uC=MCU=(Many ways to term microcontroller)

.. in the name of science

What is the name of the servo in the beginning? I am new to servos so everyone can forget nasty comments.

great video

So at some point, the servo is collapsing the wave function?

Hello tnx for t vid. Does anybody know how the komponent at 6:29 on the pcb in the upper left corner is called? Its the one on the pcb that is connected with the plus and minus cable from the servo. I think its a capacitor...? I burnd out that component on my servo, might be able to replace.... tnx for any reply

You do realize this is a tutorial series on programming microcontrollers and not related to CNC.

When can we have the next lesson about PWM

Where can I buy servos with centred shafts?

THANKS IS COOL

Is that a cordless motor of not

How can someone make a zipzap sized car drift properly?? I know the theory of weight and traction, but I don't understand electronics!

HEY, YOU ARE DOING A REALLY GOOD JOB. BUT I MUST HONESTLY SAY, FOR HEAVEN SAKE PLEASE PLEASE SPEAK MORE SLOWLY IN FUTURE, SO THAT WE CAN UNDERSTAND AND ABSORB THE CONCEPTS CLEARLY !! PLEASE DO CONSIDER MY SUGGESTION. THANK YOU !

Can I use this for the rudder on an rc boat
