hello John,
Sorry for answering late. Hope you are still interested. I decided to apply a 5V motor configuration for a 24V motor for more torque. I would like to have your opinion if it is doable or works? Here is my plan as follows:
Now I’m controlling a 5V motor with Arduino but need more torque which means a more powerful motor. Here is my scheme. (I took it form a tutorial):

Here Arduino is controlling a 5V unipolar stepper motor through a Darlington transistor.
My question is if I just change this motor with a 24V one and feed the new motor with an external 24V power supply and remain the rest configuration same would the motor still be controlled? Or do I need another configuration?
I also asked this to another forum, I hope I can learn about it.
Thanks for sparing time!
