contrôler deux moteur avec shield moteur et shield wifi

bonjour , aprés l’aide des membres de ce forum j’ai reussi à controler
deux moteur avec la carte wifi (arduino wifi shield http://arduino.cc/en/Main/ArduinoWiFiShield) et
la carte moteur [(arduino motor shield http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/?ALLSTEPS](http://(arduino motor shield http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/?ALLSTEPS)) mais le problème en pin 9
dc c’est réservé pour la crate wifi donc il presente un erreur
qui peut m’aider pour je puisse changer par exemple le moteur 2 pour
qu’il fonctionne avec un autre pin ou quoi, j’ai besion de votre aide voic mon code arduino
