Stepper Motor meets Arduino
|Stepper Motor meets Arduino|
| -Electronics: figuring out the wires of a harvested, non documented, 5-wire stepper motor
-Arduino: 101: how to code a rotation, then building upon that code
The stepper motors:
I harvested two stepper motors from an old Nec P20 Pinwriter matrix printer.
todo: add pictures
Both stepper printers have 5 wires.
This is a very useful link to figure out the wires: 
I found this code useful to start with:
