Sure, try this and see if it works. That might be related to the "different grounds" suggestion. I don't think it would hurt.

I would say yes, I can't see why the signal would be any different for what you are telling it to send out. Now, if you were sending out a PWM signal or some funky square wave or something, that would be different. But you're not.
