Stepper motor control with Arduino

Hi im new to this forum and only amateur at robotics but super keen. I was just wondering if its possible to connect a stepper motor directly to the Arduino? or will this overdraw the arduino and kill it? This is for a uni project...

The processor (ATmega328) can only deliver 40mA per pin output, so yes a stepper motor will fry it. You need a separate controller. Check Pololu or Sparkfun for possibilities.

Their drivers are pretty much breakout boards. The provide access to pins and you write the driver code yourself. The controllers typically have a higher level interface like ttl serial or RC, and it's easier to interface to them.
