I have added a corrected version of the snubber diode diagram.

I also added a buzzer so that it beeps when you turn it on per my friends request. I got the diode wired up and all is working fine now.

That motor looks like a playstation controller motor, definitely will take more than 30mA (the size of the motor gives it away),
that transistor isn't optional (unless you're happy for the Arduino to fail randomly at some point).

I'll double check. Can you point me to a transistor I could buy at radioshack?

The motor uses about 70mA

When I go to radioshack what transistor should I buy?
