    if i could… can you show how to control 20 servo with 20 pot… or just use many micro controller?
    or how to make micro c have 20 io pin

  • Reply TheOneTribble June 21, 2017 at 7:33 pm

    could a servo be made with a rotary encoder instead of a potentiometer so it can turn more than 360° but you also know the position of it?

    Hi, I am building a camera slider which will be controlled by a motor.
    I have a cheap "servo tester" which I want to use as a speed regulator, and I dont want to use a servo as it makes too much noise, can you recommend a motor that is silent and can be controlled by a 5v servo tester?

    Making an infinite rotation servo of a limited rotation servo should destroy the precision with which it rotates — perfectly defeating the purpose. Why not rather use a DC-motor and a couple of gears?

  • Reply Eddie Hart October 29, 2017 at 5:04 pm

    Would it be possible to replace the pot on the shaft with a rotary encoder and some clever circuitry to make this more like a stepper motor?

  • Reply iMeMySelf November 4, 2017 at 10:40 pm

    Let's say I wanted the server to go to -90 degrees when I push a button or flick a switch, then go back again to 0 degrees. It's for a payload release system…
    Is it possible to do this without a micro-controller? Or do I need a completely different thingy you know of, that I would require for this?

    Thank you for the video. However, it is disappointing that you spent so much time talking about servos and never once showed any practical use for them. I keep running into basic servo videos that show servos spinning around pointlessly. Can you please throw a quick video showing what can be attached to a servo motor?

    so basically the more you spend the better the servo?

  • Reply Andro January 20, 2019 at 2:40 am

    Wait, what? why hack it to rotate 360 degrees, that is essentially the same thing as a DC motor with a reduction box
    I know it is not quite the same thing, since the duty cycle of the PWM is the controller of the direction, and not the polarity of the thing, but what makes a servo really useful is the fact that you can control the angle, take that off, and it is just a modified motor :v

    I'm an autoamtion Engineer and had to use servo motor on a day to day basis on most of the ptojects.
    Usually Mitsubishi MRJE series and AB servos with the use of PLC.
    The problem is arduino projects look exciting but I don't find its real industrial applications.
    So why should I learn this?
