By energizing the coils in themotor in a particular sequence, a motor takes 48 or more small, precise steps to make one full revolution. If you are using two of these motors to driveyour robot’s wheels, you can get good control over how far it travels by makingthe motors travel x many steps forwards or backwards. That’s assuming youcan find stepper motor drivers, of course. I’ve always had problems finding good servo drivers. Once I was even reduced to using discreet components (say it isn’t so!) to drive my steppers. Then I got my hands on the L293D motor driver chip (See motors part 1) and life got a lot easier. The L293D contains two H-bridges for driving smallDC motors. Now the home-viewing audience mi ...
