I've seen the tutorial video and the sample source code for controlling motors via a H-bridge, but all these have the motors being in 4 fixed states (5 if you count stopped) Fwd, Back, Left and Right. What I want to be able to do though is have a robot turn in a more gradual manor.
If you think of a joystick, pushing forward should get gradually faster and pushing to the side should turn gradually more and more. Combinations of the two should also be possible.
I was wondering then if anyone has any code examples of controlling such a device?
