The most commonly used stepper motor is the 28-BYJ48 Stepper Motors.
You can find this (or similar) motors in your DVD drives, Motion camera
and many more place. The motor has a 4 coil unipolar arrangement and
each coil is rated for +5V hence it is relatively easy to control with
any basic microcontrollers. These motors has a stride angle of
5.625°/64, this means that the motor will have to make 64 steps to
complete one rotation and for every step it will cover a 5.625° hence
the level of control is also high.
