GND pin of the microcontroller as well to ensure that power and signals are

flowing smoothly between the motor-driver circuitry and the microcontroller.

In addition, most stepper motors require a much higher electrical current

than most microcontrollers can handle—and, though it is not shown in the

diagram on page 199, most stepper motors will require a dedicated power

supply that provides the motor with 12 V to move the motor and achieve the

strength and accuracy the motor was designed to provide.
