A 5-wire unipolar stepper motor (these could also be salvaged from old 5¼” floppy disk drives), ULN2003 IC (stepper motor driver), wire, stripboard (or a solderless breadboard ), solder and DB-25 Male connector (buy these two if you can solder. Soldering is not necessary for doing this project, but it will ensure that your connections are secure), DB25 (female/male) parallel port cable, a multimeter, a power adapter (with voltage rating depending on your motor’s requirements)
