There are several ways to do this. In Mobile Robots, they talk about H
bridge circuits. If you are doing less than 2A use a L298 and some some
clamping diodes ( these keep the driver chip from being fried when you
turn the motor off).
The L298 has 2 2A H bridge drivers on it.
For up to 5A, Bell and Glenn sells a set for driver transistors for ???.
You still have to add diodes, decoding logic, and drive logic.
5A + , you will need some heavy duty Mosfets most likely, some drive
stuff, etc, clamping diodes... Or what about relays, and forget the PWM here
