Introducing Actuators
So far, we have covered input and output on the PIC® microcontrollers. In this chapter, we apply the knowledge we learned thus far to control three common actuators in embedded systems—the DC motor, the stepper motor, and the servo motor. We incrementally examine these three actuators based on their ability to be controlled. We start with the DC motor, which has very coarse control of directionality (forward or backward) and is the easiest to control. Next, we look at the servo, which has a greater degree of ability to be controlled, ...
