I am having a problem using the MotorShield (the one specified on this site) in tandem with the Arduino. I am using the Motorshield to power some dinky DC motors (2-4V). If I connect the Arduino (Uno) and Motorshield's Vin to a 9.6V, 2000mAh battery it provides way too much current to the motors (as I under the motorshield does not regulate voltage at all). However, if I say, power the Arduino with USB (Vin's are untied) and the motorshield with a voltage divided 3.5 V, the motors do not work.
I am relatively inexperienced and am sure it is an easy fix, but for the life of me I can't seem to find it. I don't think the voltage divider should be sucking that much current off the battery. Any help or insight would be appreciated. Thanks!
