I am after a PWM circuit that can be used to help me build a two wheeled carry cart. I will want to be able to control the the speed of two motors so I can intiate turns. Skid steer is the term I think. Forward and reverse also required. Control of cart will be done from a handheld unit connected by umbilical. Unsure as to put circuits with the switches in the handheld or in the cart with the batteries and motors. Any advice or help would be useful. Please don't suggest looking for help in the library or search engines as their seem to be so many variations of the PWM circuits and I have no idea which would suit my task.
Many Thank
