A Servo is a regular motor, meaning when you add power to the 2 leeds
the moter will spin, a servo have some electronics and gearing added so
the number of rotations (before gearing) is limited by how long time you
have added the power (eg pulse width).

A bipolar stepper have 4 coils (5 leads) that you power in sequence to
make it rotate, hence just adding power will not rotate it.

A unipolar steeper is more or less the same, but with an extra wire,
that i think is some sort of enable, but i might be wrong...

Also, what is the difference between a servo and a stepper motor?
