How can I control bipolar motors whit BX24 , and how can I conect ULN2003
amplifier?

Tengo proyectos interactivos, si deseea cruzar informaci'on no dude en
escribirme, soy estudiante de artes pl'asticas.

The ULN2003 would normally be used to drive unipolor stepper motors
(as well as other high current devices). For bipolor steppers, you
need a bipolar driver such as the L293D or L298N

I would suggest that you get the book "Easy Step'n" by David Benson.
It has a lot of information on stepper motors and driver circuits.
Most of the examples use a PIC microcontroller but the concepts are
exactly the same as you would use with a BX-24. The book is
available from several sources including http://www.stepperstuff.com.
