Control System Fundamentals

A controller actively changes the motor output to move the system closer to a desired value, known as the set point.

Stepper Motors

Steppers are motors that rotate a specific number of degrees in response to control pulses. The number of degrees in each step is motor-dependent, typically ranging from 1 to 30 degrees.

Steppers commonly used with Arduino include:

• Bipolar: Typically with four leads attached to two coils.
• Unipolar: Five or six leads attached to two coils.
