I love how I am learning about the components but also how to be clever with a breadboard. Great vid. Please keep making more.

[@akkirinnovatetechnologies1438]

Hi , i also create some content about electronic..take a look and subscribe ...thanks

[@xyz.5512]

this is very well explained. i needed breakdown for my project of "robotic arm using servo and POT" and this provided me everything i needed to know. thanks!

[@LIJOYDesininja]

how much code full with the bround caulour also or only colered

[@TimRoot-dotcom]

excellent. you have a great teaching style. im hoping you make more arduino tutorials!

[@DroneHow]

+Tim Root Thanks, Tim. Stayed tuned for more such tutorials

[@junkstudios8774]

I should accept in that

[@chintan965]

Drone How I don't know why my servo keeps shaking and acting weird. Can you please help me out

I have just started Arduino and your tutorial was just exceptional!! Thank you and keep on doing the good job.

[@MadGod-ju5gr]

The best totural i have ever seen this helped in my science project with an A+

[@rajoak3097]

Hey really nice video, initially it was not working so I changed the theta to zero and now it's working well!

[@corado9923]

It's not working for me rn, can you explain?

[@cheskaabarro4658]

More tutorials please. I'm new to arduino and your video is really helping me. You are great in teaching! More tutorial pleaseeeee

[@marcusfunchar7060]

Please do more arduino videos they are so clear to understand even the code is easy to get. I just got my arduino starter kit today and I know nothings about arduinos but your videos helped me start playing with it. Thanks so much

[@HamidSBaig]

Nice explanation for an Arduino beginner like me. Thanks.

What if i have to use 4 servos at once

[@bridgetteh8372]

Thank you! I really hope you do more arduino tutorials! Yours are the easiest to follow!

[@DroneHow]

+Bridgette H Thank you very much.

[@MrYeshwanthln]

Presentation is perfect ! very clear and to the point (Y)

[@DroneHow]

Thank you!

[@darionmackey5090]

I had a problem with shaky motor around 120 deg it would start going crazy. If you have this problem you can smooth out the movement with a capacitor wired in series with the POT. In my case 100 ųF capacitor worked great.

[@grimr27]

thank you for this tutorial. You do a great job and are easy to follow along with. hope to see more on the arduino.

[@corbintriano6148]

Excellent video. I found it holding my interest while being able to easily follow along=)

Will do!

[@pusska0]

Hi, Awsome video. How would I Add another potentiometer to this circut? So I can control one servo from two potentiometers. I have managed to get one servo opperating with one pot but not two. thanks for any feedback provided.

[@jflow_07]

This was very clear. Thank you!

[@patelchiraag]

#include Servo myservo; // create servo object to control a servo int potpin = 0; // analog pin used to connect the potentiometer int val; // variable to read the value from the analog pin void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023) myservo.write(val); // sets the servo position according to the scaled value delay(15); // waits for the servo to get there } What will be the output of above code? a. read the potentiometr value on A0 only b. read the potentiometr value on A0 and writes to servo controller in a loop after a delay of 15 miliseconds c.write value to servo motor only d. Non of above

[@astridtrent]

it would be A. Because you are not converting the analog value into a value that the servo can read.

[@manolotrlolo]

Is there a way to directly input data from a PC to an arduino? As an example, if I'd want to turn the servo by 45 degrees, could I simply type it in my PC and send it directly to the Arduino a.k.a the servo?

[@TrungTran-hw7ws]

your sound feel so good to me

[@henkdev1476]

This tutorial was amazing i subbed

[@chickenwings79]

Please make a 2020 video this will be amazing

[@johnvincentarabejo1294]

Thank you for the "any potentiometer you want" ^__^ other vid uses only 10k ohms

[@gunzi2269]

Thank you for this well explained tutorial!!!

[@amishashethia4902]

[@diamony123]

great tutorial, any idea how you would use a pot to display 10 images on a tft display as you turn the pot to select back and forth the images.

[@antobs3680]

Great explanation. Thank you for making awesome videos

[@alishawasthi8837]

Great tutorial.🔥🔥🔥

[@5xgreentv33]

My servo has a mine of its own I can’t control it by the potentiometer it goes back and forward really fast plz help

[@rushikeshthorat8902]

Increase the delay

[@AO-lq9dq]

great content thank you so much

[@SneekyFab]

I just tried running this code with an external power supply made from AA batteries so that I could run more than one servo, but the servo keeps shaking back and forth randomly when I do so. Is there a different way you need to write the code to use 5V external rather than the 5V on the arduino?

[@who-is8cu]

Can I do this twice on the same board, but on different sides

[@dipeshbhushan3929]

sir in my case my servo keeps on rotating please help me sir

[@mohdfaridrozali3319]

Thanks for your guide😊

[@bigbhai2721]

Nice video.

[@pokeethan]

Really helpful

[@x-6790]

From where you purchased all components.?

[@joryaock]

Can I use any potentiometer or are there certain ones that are compatible with an Arduino?

[@vedansh29]

Very well explained

[@adityarajvanshi1]

It's great Drone How

[@paulocastro9277]

Hi!!! Please, can I include a position readout on a OLED display returning the information of the servo in degrees??? Thanks so much and at last, thanks too for the great tutorial!!! Regards!!!

[@the_clockwork_jackass6897]

The 5v connection in 1:34 is tomato colored And there's a glimpse into what my head is like

[@syuesalim6933]

wow it does work! BUT why when i use batery it work like SLOW

[@Rocky-cj2gz]

can we do this with mirco servo?

[@madhukeshnp]

Please add a push button to rest the position of the servo to Home position. That is the pos= 0;

[@abuhanifazulkafli1683]

thanks. this help me alot.. but.. can this potentiometer control the motor from 0 to 360 degrees??

[@CarbonAnimationProductions]

mine is just rotating back n forth instead of going right or left

[@Deltagamerz]

Yes same now it's my servo isn't rotating

[@CarbonAnimationProductions]

@@Deltagamerz i figured it out, you have to connect the terminals of the poteniometer with the rest of the wiring on the breadboard. he must have edited it out of his video or something but thats what fixed mine

[@Deltagamerz]

@@CarbonAnimationProductions please explain 😭

[@CarbonAnimationProductions]

@@Deltagamerz lol okay so where the wires are at the end of the breadboard, you need to connect the poteniometer's positive and negative over there so they all share power

[@Deltagamerz]

@@CarbonAnimationProductions thanks but i figured out it at 12:30 am in morning

[@Limaokinzoks]

i wanna ask can i make the servo rotate more than 180 i mean like full rotation 360 degrees or no??

[@grahamtech]

what about external power source?

[@jacktan9336]

can i ask are there any application of this in any real world scenario?

[@RMXSteel]

how many ohm is the potentiometer, i m gonna usa a 25kg servo

[@adityarajvanshi1]

I have seen all video

[@ethanschwall6853]

I have a smaller breadboard with only 30 rows, could I put the potentiometer between row 25 and 30?

[@jamesking5665]

what progrmaming changes are required to power two servos, with identical motion?

[@sergecampeau2844]

I don't understand the link between your 180 value and the servo. The servo does not care about the angle, it is just looking for the pulse width from 1 to 2 mS. Right?

[@ХамудБатуль]

Yeah .. you're right ..

[@elbertmoria9299]

Can I use a 360 continuos servo and continuos potentiometer?

[@tahooraahmadi1417]

can you write the code for this project and not using the servo library but instead use micros and millis

[@bessalf]

Hi, great tutorial.. thank you!! I wanted to do an electronic airplane trim for my simulator. I have purchased a trim wheel on ebay and I will connect it to the simulator/computer. My idea is that when I use the trim on the yoke, the servo control turns the trim wheels. Having that I have a few questions: 1) Is it okay to turn the servo manually? 2) Do you think this servo is strong enough to turn a airplane trim wheel? 3) Using your program.. can it read the input from the pc rather than the potentiometer with an small adjustment? Thanks,

[@DroneHow]

+Filipe Bessa Now when you say simulator, what kind of simulator are you specifically referring to and what size aircraft are you looking into?

[@bessalf]

+Drone How I'm bulding a simulator for a Piper Seneca V! I've bought two trim wheels on ebay! My idea is to control these two wheels electronically using the servos when I activate it through the yoke, but in some ocasions I would turn these wheels manually! The mechanic turn will be translated, visa reduction gears, to a rotary potentiometer, which I can then read on the simulator software!

[@DroneHow]

+Filipe Bessa I would first recommend doing a torque reading when manually turning the wheels. Once you have the torque reading, I would find a servo that can handle at least twice the torque required. Nothing in the code or arduino would change. If the servo has a higher current rating, you'll need to power the servo directly, so as to prevent overloading the arduino.

[@DroneHow]

+Filipe Bessa You can certainly turn the servos manually, provided there is no power to the servo when turning it. Are you looking to drive the servo through more than 180 degrees of rotation?

[@bessalf]

+Drone How thanks for replying! I think the wheels are not that heavy to turn, so probably the servo you used should be able to turn it, but I can go stronger if needed! The rotation will depend on the reduction gears! The servo should turn at least the same as the rotary potentiometer in your video! I've seen a couple of videos on how to hack a servo for continuous rotation if I need a greater turn!

[@qwertyproductions4109]

thanks

[@UltraBigChungus]

i have this problem where as soon as my servo reaches 180 it keeps going around in circles I need a fix..

[@tomjarosz]

All awesome

[@newtonsingh2188]

can you please explain how to make this simple circuit wireless

[@patriksladcik3347]

Theoretically could you have connected for instance 4 servos and 4 potentiometers?

[@DroneHow]

Yes, I don't see why not.

[@sergecampeau2844]

What is this programming language? Is it complicated to learn? Would it be possible to set a more complex rule with look-up table?

[@Charlie-wu6bm]

Serge Campeau the programming language is based off java so is pretty easy to learn. it has been simplified with modules which does most of the work for you.

[@andrew.k3002]

why does my servo motor just go crazy when i turn the potentiometer to the right?

[@visionaryrobotics4065]

how many servos can i connect to my arduino until i need a different power supply?
