Hi! I made this circuit to control a transistor, but I realized that I don't know how to ground it properly. Is it okay to do what I did in this schematic? (Note that the Arduino has its own power supply.) http://bayimg.com/PAMpcaacP

Circuitry: is this bad?

Thanks to all of you!
I still have a lot to learn, apparently
