Thanks for the tip. I got a hold of the book and read some of it.
:)
I was wondering if sending pulses to the motor would cause "choppy" rotation....or does it occur so fast that inertia effects make it "smooth".
Also, with an h-bridge, is it possible to modify the switching to make the speed of the motors vary at finer increments than 8? Is the 8 levels deal part of the handyboard design or the motor chips.
