EXPERIMENT #27: STEPPER MOTOR CONTROL
This experiment demonstrates the control of a small 12-volt stepper motor. Stepper
motors convert a pattern of inputs and the rate-of-change of those inputs into
precise rotational motion. The rotational angle and direction for each change (step)
is determined by the construction of the motor as well as the step pattern input.
Stepper motors are used as precision positioning devices in robotics and industrial
control applications.
