In this chapter, you will look at controlling two useful types of DC motors. They are
The stepper motor
The servo motor
You will learn how they work and how you can use the PIC micro to control them.
With reference to the servo motor, you will also look at using an analog input, such as a variable voltage, to control the position of the motor.
The Stepper Motor
The stepper motor is a DC motor that has a number of coils encased in the stator part of the motor. To make the rotor rotate, each of the coils in the stator are turned on sequentially so the rotor rotates in steps because ...
