Same external power supply for arduino and motor shield?

Hi Guys,

Can I use same 12 V wall wart power supply for arduino uno and arduino motor shield R3?

The motor shield is connected to a stepper motor.

Regards,

Is this the same motor you already asked about? If so please don't cross-post.

If not then perhaps you realize what you've omitted from your post (ie enough detail).

In general using the same supply is fraught with problems, but without information about the motor there's nothing definite to say.
