Salut
Je te conseille de ne pas utiliser l'arduino comme alimentation de tes moteurs, tu devrais utiliser une interface basée sur un transistor de puissance. Un NMOS ferait l'affaire tu câbleras ton pwm sur le G du transistor ton alimentation externe sur le D et le S sur ton moteur, l'autre fil du moteur sera cablé sur la masse sur un shcéma c'est plus parlant je te conseille de regarder le premier schéma de ce pdf http://dualsnake.free.fr/documents/BTS1/ESTI/3525.pdf.Le VG correspond au PWM fournit par ton arduino. Tu peux voir visualiser le résultat sur mes projets voici le lien http://www.youtube.com/user/ahamedBacar.
