Stepper Motor (by Zoran)
I need to control stepper motor in very small steps which I can control with buttons similar like in example but more precise.

Stepping the motor is relatively simple and easy.

Microstepping is equally easy provided you have a stepper motor driver capable of microstepping.

both kinds of drivers ( external power switches ) require either a step and direction input signals alternatively clock wise step and counter clock wise step signals.

use pot. (by mehmet)
hi,
I want to use a pot, not a +,- button. how can I make changes?

Some issues when driving a stepper motor (by Ziggy)
There are many on line resources to describe the problems of micro stepping a stepper motor.
The following link

https://www.zaber.com/microstepping-tutorial

describes micro stepping in terms of motor coil current phaser.
( a phaser is a vectorial representation of current or voltage as a complex rotating vector )

A stepper motor can step from stable pole position to stable pole position when coils are digitally driven either high or low ( in a particular sequence,

Micro stepping is driving coil in an analog fashion( modulating phase and magnitude of the coil current).

Stepping a stepper can be achieved through the use of simple switching schema whereas micro stepping is quite a deal more complex and requires a specialised driver in order to provide the required current phase and and magnitude.
