I am creating a project that uses Bluetooth, But unfortunately it requires some kind of control of the range. I was thinking a potentiometer controlling the power going to the transmitters antenna. But I have no clue how I would program this. Can anyone help me out or point me in the right direction? Thanks
EDIT Okay I am making this because I am designing a sensor that tells if you are in a room. For example when you leave the room the Bluetooth single is no longer in range then it notifies the arduino. I am not sure if you can do this but I cant see why not.
