Simples rotação num sentido

* Program to drive a stepper motor coming from a 5’25 disk drive
* according to the documentation I found, this stepper: “[…] motor
* made by Copal Electronics, with 1.8 degrees per step and 96 ohms
* per winding, with center taps brought out to separate leads […]”
* [http://www.cs.uiowa.edu/~jones/step/example.html]
*
* It is a unipolar stepper motor with 5 wires:
*
* – red: power connector, I have it at 5V and works fine
* – orange and black: coil 1
* – brown and yellow: coil 2
