Hi.

I have a stepper motor connected to my Arduino Duemilanove
through an Adafruit motorshield.

I find that the motor is horribly underpowered.  I'm not
doing anything especially difficult with the motor... but it
is stopped easily under minimal load.

Am I doing anything wrong?  Is there a way to add an
external power supply while still using the motorshield?

Thanks for any advice.
Paul. :(
