RoscoBell:
My setup looks more or less like this
And, more or less, junk. God only knows how kosher it is to put 4xAA on the Arduino's 5v pin but, if you get rid of the resistor and connect bluetooth ground properly to ground like the sign on it says, it might actually work. As things are, it IS kosher to have 6v on bluetooth and, since Arduino is just a bystander, you can test for your Bluetooth<>Android connection with it disconnected.
