PBD3517 
PBD3517.fzpz ( use Fritzing: Stepper Motor - Unipolar)
Used as an add on to any of our PIC-equipments. Borrow a 6V battery ant try out the equipment. Note that the step-button lacks debounce circuit.
To connect a PIC-processor - remowe the switches and connect the wires acording to the figure.
Push button switch
Slide switch
Potentiometer 1k (variable resistor)
