How Servo Motors Work & How To Control Servos using Arduino

   Hey, could you explain exactly how one could go about determining the exact pulse widths which correspond to 0° and 180° (in the case that they're not the usual 1ms-2ms)? Is it just trial and error? If I set a pulse width that is lower than the allowed pulse width for 0°, would I damage the servo? Thank you!

   I really appreciate how he says that he bought a cheaper copy instead of acting like it’s the actual thing

   Thank you for the tutorial, that was super useful, going to play with a pca9685 😀

4. 

   Nice LOGO 😀

5. 

   Damn… my mind is in the gutter "..to precisely control the position of the shaft"… and it was all downhill from there.

6. 

   is there a reason why you didn't show the second instance you created for the second servo down in the loop? i mean i dont even see this particular sketch in your website whats going on ?

7. 

   I wonder if you can use this to teach make a bigger Servo for a bigger kinds of robots

   With yours, what is the different between servo motor and stepper motor? What I understand about servo motor is that it can detect the best signal, so it used to trace the best signal like in antenna parabola. But what you did here is to turn the servo to a specific direction, which it mostly like in stepper motor.

    V1:20:22: error: no matching function for call to 'init(int)'

    driver.init(B000000); // Address pins A5-A0 set to B000000

    Have any one try to upload the code…?

    Excellent videos as always. Thanks for producing these.

    hi can i use a servos to make a cardboard glider land to a specific location?

13. 

    WOW THANK YOU SO MUCH

14. 

    Anyone know possible causes for a servo motor showing an "overvoltage" fault?

15. 

    Hello sir Servo Motor collector program

16. 

    i didnt uderstand

17. 

    Great instructions! I have interested in this since I found some projects using Arduino. And I am more interested in building a tracking device to control a pan and tilt motor. If you have a chance or time to help me I can explain in more detail. Thanks

18. 

    great video! but how much voltage the mini DC motor works?

19. 

    And still, no one told me how the motor remains in it's position with heavy load after it reaches it's target. ?

20. 

    Very good explanation!

21. 

    Svaka čast Dejane! 🙂

22. 

    Just a question,, if we replace that small motor with a bigger motor. For more power… How can we give more power supply like 50w…..

    OK can you provide a video by which we can convert a big DC motor to servo like this…having bigger and more power

23. 

    which coding language is that?

24. 

    PCA9685_ServoEvaluator' does not name a type
    
    I get this error, can you help ?

25. 

    How do you rotate servo 180° in reverse?

26. 

    I’d like to make my own servers for the robot I’m making How can I do that?

    Hi sir can we connect each possition degrees with lcd. Like 45,90,180

    Great

30. 

    omg ,you are the best ,thank you so much

31. 

    great

32. 

    High teacher!thank u

33. 

    nice sir update whats app: 8971492162

    Ho bisogno di circa 25 circuiti stampati per servo verricello da modellismo. Qualcuno può aiutarmi grazie

35. 

    I like you ..thanks admin

36. 

    Is it possible to rotate this motor to any angle other than 0, 90 and 180 degrees?

37. 

    can the dc motor replaced by larger dc motor so it can have more power?

38. 

    GOOD

39. 

    superb

    Hello Sir, is it possible to apply this PCA using matlab? I tried in matlab but the PCA library is not provided, it only provide Adafruit Motor Shield V2

    How to control 360 servo motor in increase 45 degree sequence???

44. 

    Sir, your channel is aewsome. Hope you can keep bringing us high quality content like this. Thank you!

45. 

    Thank you. I can fix my servo because of this video.

47. 

    There are use stepper motor in robotic nor servo motor..

48. 

    does the pulse always be 20ms??

49. 

    Could plz make video how to build app to control(on and off position) remotely(by sending sms)the ball valves with servo motors ?
