Multiple Servo Control with Potentiometers and Arduino

In this tutorial, we will learn how to use multi-servo with potentiometer. We will control 4 pcs servo motor with 4 pcs potentiometer. You can implement your robotic arm projects with reference to this tutorial. Of course we will use external battery / power when doing this.
In the next tutorial, I'll show you how to control servo motor with joystick. Do not forget to subscribe. Thank you for your support. I did not share the code because it is short and it varies according to the number of servo,potentiometer. You can write code by watching the tutorial. This is a better way to learn. I will continue to share long and complex codes.

[@underwaterchippie]

Great tutorial. However, I don't get to work with my "MeArm" robotic arm. My lecturer had I quick look at it, tested all the four potentiometers and said that there is no enough current for the motors... Im using the same mini servos(tower 9g), 10k pot, arduino Uno and your code. Hope to hear from you! cheers

[@kenichi5717]

(soryy im 6 years late) anyways if your still having trouble.. u can try to use an external battery supply, maybe dont use ur arduino's 5v u could instead connect a 9v battery to the railings in the breaboard that will supply servo and potentiometer. for arduino u can use the same as before. hope this helps!!

trying to get two mg996r 4.8v - 6v 180degree servos to be controlled by pots both B10k, however for the life of me i cant make them budge with the pot. i have a separate supply source( Supplies 5v) , ive more than once gone through Merts' videos to see if there was any error in the coding and wiring. the code and wiring set up works for SG servos but just not my mg996r. suggestions? not enough power from supply? maybe defective product? Mg996r servos are from Tiankongrc

[@estebansanchez676]

BTW wiring does include GRD connection between power supply and arduino uno. And just tried it using only the arduino power source 5v for both mg996r and pots and actually works but still has a few kinks (twitching) by viewing merts' videos i came to understand that you diminish the kinks by adding a separate power supply, but when i do that the servos stop reading the pot

?is it better to control servos with potentiometer or joystick thumb also i couldnt write a code to control servo with joystick the same way you control it with pot cuz when the joystick back to base the servo too . i hope you get what i mean

[@malcolmpalmer2437]

My first attempt resulted in servo twitching. Then I realised you had connected the servo positives to the same rail as the pots but didn't connect the Arduino VCC. So I changed the servo positives and the positive from the external battery to a separate positive rail, kept the battery and pots ground in the same ground as the pots and connected the Arduino VCC to the pots positive rail. This worked a treat. Now everything works smoothly. If anybody is interested in a Fritzing diagram, I'll post one.

[@arjaystephenebonostro9691]

[@malcolmpalmer2437]

There are plenty of Arduino Tutorials on the web including those in Arduino's actual website. In this particular case you will see the Coding in the video at position 5:37. Also you will find how to code potentiometers in the File, Examples in the Arduino menu. You will learn a lot quicker by buying a good Arduino book instead of copying codes. And Experiement ........

Hi I tested this set up i while ago, and it worked perfectly. I was working on something else and now im back into my project that i need this agin. Btw, great video :) Before there was no servo jitter, now it is alot. I tried to connect only one. A1 and 3. I tried to connect the same on A2 and 5, but nothing happens. Could this mean that its a bad arduino? I think its the same i used earlier. Even tried with a Nano, same result.

Awesome vid! There is only one problem: When I turn on my Arduino, the motors become very shaky and wobble everywhere. I am using this in a robotic arm, and they are PowerHD 1501MG servo motors. Do you think this problem is from the motor type/voltage or the setup in the robotic arm? Thanks!

Hi.... Where coding arduino with Potentiometers ? I need coding that please

[@luizalmeida1209]

What do you need? It's not very complicated, as you can see in the video, he's using analog read do read the output on the potentiometer and writing the value he gets into the servo's angle. If you want to control something directly with the potentiometer you just need to plug that middle pin as the input energy of whatever you want to control. If you give me more detail maybe I can help you better

[@jonahrubin9989]

I've tried recreating this setup twice with the same code, but I can't get it working. Some potentiometers affect all four servos, and some affect none. My potentiometers are 2k not 10k. Could this be the issue? If not, do you know what could?
