This is a library that drives a stepper motor with given parameters for speed and direction.
About
This is a stepper motor library that is based on the sMotor library by Samuel Matildes (sam.naeec@gmail.com). It was designed to drive specifically a 5718m-05e-05 stepper motor in conjunction with an L293NE quad h-bridge chip. I am not responsible for any damage caused due to the execution of this program on your hardware as I can only confirm that it works for the above specified model. High torque mode is currently not complete.
