Powering the tiniest stepper motor

Getting this micro bipolar stepper motor to do what I want was probably one of the hardest things Ive ever had to learn.

These inexpensive stepper motors are from china and there isnt much documentation and I couldnt find any existing code to base off of. So i had to tackle this on my own. Hadd to learn about steps per revolution, PWM, drivers, etc.

Anyways I wound up running L2938 H Driver powered by attiny85 micro controller unfortunately the torque on these motors didnt wind up sufficing for our project, but now I can control just about any stepper motor in the future which im sure will be useful at some point.
