With some applications a stepper motor is prefered over a servo. For instance for the continuous rotation of say a wind mill model. Or with applications like a turn table, a linear shift table or an elevator, a stepper motor can be of great help thanks to the accurate positioning that is possible.
In this video we connect a very cheap (less than $2,-) toy motor to our Arduino and run it. In the coming videos we'll look at features like change directon, speed control and accurate positioning, and we'll look at more powerful motors and drivers.
