Use of backdriven stepper motor as switch?

Using Arduino Project Guidance
1

Greetings,

I am working on a project that includes 3 stepper motors, and am wondering if after the motors are driven by my UNO if I can backdrive them and use that as a button press input

A stepper motor being turned manually will generate a voltage so may be able to be sensed and read into your code.

Hi,
What is the application, and how are you driving your steppers.
When you drive the shaft the windings will produce a voltage, but it can be higher than the 5V or 3.3V logic that your arduino uses.
Use a separate button.
