 Bigger Bigger  Smaller Smaller  Reset Reset

I have been reading for hours now on the forum and various places around the web, but still can't seem to find the exact answer.

My DC motor http://www.grainger.com/Grainger/DAYTON-DC-Motor-3LCH7?Pid=search is going to be powered by http://www.grainger.com/Grainger/RAYOVAC-Lantern-Battery-5U056?Pid=search.

I have the Arduino already, but my problem comes because the motor runs at 3.8a continuously and I dont want to burn out the Arduino since the whole thing would be running continuously for many hours per day

I will also be connecting an H-Bridge to it since I need the motor to go both clockwise and counterclockwise

Thanks for anyone that could help out at all.

I think you misunderstand the way electricity works, I'm afraid.

The fact that your motors will draw 3.8A will have no effect on your arduino whatsoever unless you were to wire it in series (you're not going to wire it in series, don't worry - you have to have some very messed up wiring to do that.)

That non-rechargeable battery is going to drive your motor continuously,   for about ten minutes.

You'd better buy thousands of those batteries.
