arduino unipolar motor stepper

Après avoir cru que mon moteur était mal branché il s'agissait plutôt de mon code!

J'utilisait la bibliothèque stepper, peut être un peu mal calibré. La le moteur tourne gentiment dans le sens des aiguilles d'une montre.

Commun : Noir

phase A : Rouge

phase B : blanc

Phase C : Marron

Phase D : vert

Note avec mon moteur descendre sous les 5 ms de delay n'est pas possible.

Code arduino

/* Stepper Copal

* -------------

*

* 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
