I bought the Arduino Experimentation kit from Adafruit and have been slowly adding parts from eBay in the last week or so. I want to add a stepper motor, but I'm unsure of the hardware required to interface and control it. I don't really want to invest in the motor shield quite yet, so I'd like to do it with my existing components.
What elements do I need to connect with the motor? Many of the tutorials I've seen show an "array" or something else.
