Any good tutorial of how to control a small 4.5v dc motor with arduino?

IF it's hardware advice you want then try here Although not directly for the 'duino it is still applicable

Software you will have to look for suitable library programmes or write your own - That's why I don't use them the Picaxe is much easier IMHO.

Either search here on instructables or check out Arduino.cc

I would also put a diode in parallel with the motor ("pointing" towards the positive supply) for protection.
