  StepperMotors/28BYJ48/StepperLibraryDrive
  This program demonstrates using the standard Stepper library
  to drive a unipolar 28YBT-48 stepper motor.

  The standard Stepper library requires re-mapping of the control pins in 1-3-2-4 sequence as follows:

  Step C0 C1 C2 C3  <= as driven by the Stepper library
     1  1  0  1  0
     2  0  1  1  0
     3  0  1  0  1
     4  1  0  0  1
  Pin: I1 I3 I2 I4  <= remapped to the 28YBT-48/X113647 inputs
