This is a tutorial about using a P-Channel Enchantment Type MOSFET as a switch to turn ON and OFF a 12V Motor.
UPDATE:
You should also add a 100-ohm resistor between the Arduino pin and the Gate terminal of the MOSFET. The MOSFET has a small capacitance that starts to charge/discharge when you switch the Arduino pin. This creates a short current spike that can be bad for the Arduino pin. Especially if you plan to do high-frequency switching.

I am using an IRF9540N, but you can use some other logic level P-Channel Enchantment Type MOSFET.
