Controlling a knob using a stepper motor?

Community Projects

I have an object where I want to move it up and down using a knob. The motor I am using stepper motor

I’m trying but I still can’t find a question in your post.

So what is it that you need help with?

I’m with Phalanx on this one. Use Google to find your answer. I will tell you that you need more than a stepper and a knob, you’re going to need a stepper driver and microcontroller plus any supporting components.

Invoking Carnac at this point would be “piling on”, wouldn’t it ? :twisted:

I was so tempted to post the picture but decided not to. I'm getting soft.

Sorry about my vague question but my question was should I use Arduino to control the stepper motor or something else?

You can use any microcontroller you want. Arduino is the most common and has plenty of tutorials.

Your first post isn’t just vague. It seems contradicting.

Is the knob to be moved by the motor, … or is the knob used to direct the motor rotation? Taking aside the question whatever thing drives the motor. Oh yeah, something needs to be lifted… by the motor, or the knob?

Please give a better description of what you want to do in your project. Bad questions get bad answers. Just because we don’t understand what you want. Not because we want to make fun of you.

You would need a stepper motor driver to go between the Arduino and the motor.

Then you would need something to attach the knob to that could be read by the Arduino. That might be a potentiometer or a rotary encoder or ???

Presumably you want to be able to position this thing-to-be-raised-and-lowered somewhere between top and bottom, as dialed up via the knob. So then you have to ask yourself if the motor can hold the weight in place ? Are you using a counterbalance of some sort or will you need a brake in the system ?
