So far, we have covered input and output on the PIC microcontrollers as well as internal modules including the PWM module provided by the microcontroller. 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 ...
