Re: arduino help
pardoning the broken speech, a relay will sufice if you just need the motor to spin one way.
You should NEVER source drive current from an arduino. Each pin is wired for only 20ma. You should source your motor current from the main bus rails of whatever you are building. If you are bent on only needing 3.3v, then you should use something like an LM317 to drop the voltage.
