Rhythmic audio stepper motor

[jorginho1877]

Hello everyone

I am creating a project to move stepper motors with the rhythm of the music, however I don't know which controller to use to be able to move the motors.

How do you want the stepper to move relative to the music?

How do you want the stepper to move relative to the music?

That the motor moves with respect to the sound movements of a song such as the bass, through the use of a microphone that converts that analog signal into digital to move the stepper

Back in the 80s/90s the commodore 64 had a floppy drive that people programmed to play music using it's stepper motor. Moving forward it seems someone used multiple floppy drives to play toccata. Is this what you mean? Or do you want it to dance?

There are articles/plans/PCBs out there for driving RC servos with audio.

What are you intending the motor to move?

This should work for just spinning motors

This is better if you need some power.

The stepper motor moves in a sequence when listening to music

some mirrors that have each of the stepper motor

I think you need to do a much better job of describing what you are trying to do. Some characteristic of sound will move the stepper - ok, *what* characteristic? Frequency, volume, presence / absence, or ?

Let me give you a very simple example...

That is a very low cost, toy-like circuit - you can see the schematic **broken link removed** and many other places. Basically, the sound will clock the decade counter and sequence the LEDs....very simple.

You could do something like that, but you are not going to be able to move the stepper motor as fast as the LEDs and, of course, moving the stepper is not as simple as turning on/off an LED.

I think that there may be many ways to do what you want....once you know what you want to do.
