Example program to exercise and use with the ElectronicKit.com EKT-1016 Power Digital Shield:

Here is a sketch that will work without modifications with the EKT-1016 card (EKT1016 Tindie). It will run in several stepping modes for both bipolar and unipolar stepper motors.

Your code invokes the appropriate routine with a true/false parameter to move 1 step ahead/back respectively.

This sketch works with the factory default jumper settings on the EKT-1016.

Note that the user turns a power driver output ON by setting its port binary bit to a '0' and OFF with a '1'.
