stepper motor

Hello everybody
I have to use a stepper motor for a project at school.
I use this stepper motor
http://www.gotronic.fr/art-moteur-17hs15-0404s-18354.htm
and this dual bridge
http://www.gotronic.fr/art-commande-de-2-moteurs-rb01c025-19030.htm

I made the circuit as the picture.

I would like to have an acceleration then constant speed then deceleration.
I tried this programme :
#include <Stepper.h>
int Pin_2 = 2;
int Pin_3 = 3;
int Pin_4 = 4;
int Pin_5 = 5;
int ENA=10;
int ENB=9;
Stepper stepper(200, 2, 3, 4, 5);

void setup()
{
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
}
void loop()
{

for(int i=0;i<=255;i++)
{
analogWrite(ENA, i);
stepper.step(50);
}

delay(200);
{
for(int i=255;i>=0;i--)
{
analogWrite(ENB, i);
stepper.step(-50);
}
}
delay(200);
}

I feel the motor would me to move, it vibers, but nothing happens!
Thanks, and sorry for my english

Stepper motors do not use direction pins. Step a positive amount, and the stepper goes one way. Step a negative amount, and the stepper goes the other way.

You most certainly do not use analogWrite() to control direction.

I feel the motor would me to move, it vibers, but nothing happens!

Likely that the wires are not connected in the right order, then.

What kind of power supply are you using?

If you want acceleration use the AccelStepper library.
