instances in which servos make the most sense, and others in
which steppers make the most sense. Becoming familiar with both
is a great way to ensure that you’re ready for whatever robotics-
engineering challenge comes your way.
SAMPLE STEPPERMOTOR WIRING
Most common stepper motors have
four wires, representing two connectors
per coil of wire within the motor. Unlike
servos, stepper motors require an
additional external motor-driver circuit
in order to move. Many popular stepper-
motor drivers are available, and many of
