Post subject:  Help with Motors Please!

I am trying to run 2 of these motors ( http://www.radioshack.com/product/index.jsp?productId=2102828&znt_campaign=Category_CMS&znt_source=CAT&znt_medium=RSCOM&znt_content=CT2032230 ) using the arduino for a prototype remote control car almost. The only problem is that i want to know how to make them go forwards and backwards. Now i figured i would at least be able to get them to go forward on my own without a shield, but i cant seem to get them running. Any ideas on how i should run them or how if i absolutely need one what shield i should get?

Thanks :-)

Find a way to reverse polarity. If you cant get that to work within the software do it in the hard ware. Have one set of +/- ports attached to the motor one way and then another attached the other way. Then in your software, if you want the motor to spin forwards, power the first set of ports, for backwards, the second set of ports.
