Help controlling a dc motor with a h-bridge

I wanna use a h bridge to control a dc motor on 10 volts but i do not want to damage arduino with this external power. any suggestion? than 8-)ks

How much current doe do the motor(s) use if it under 1A use a L293D IC Or if it uses less then 2A use a SN754410.

Or if your hbridge is already working use transistors to control them by 5v (arduino)
