- Stepper Motor Control - one revolution
-
- Revisionato per i motori 5v 28YBJ-48 con controller board
- - http://arduino-info.wikispaces.com/SmallSteppers
-
- This program drives a unipolar or bipolar stepper motor.
- The motor is attached to digital pins 8 - 11 of the Arduino.
-
- The motor should revolve one revolution in one direction, then
- one revolution in the other direction.
