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?
