rookie--PIR,, bluetooth, android phone

I just found Aruino and have been tinkering around and having a lot of fun.

I have made my 1st two projects

  1. motion sensor PIR that turns on a LED and put a peizo on it too. :o

  2. LED turns on with android through blue tooth.

I would like to use pir to use bluetooth and send me a message thru android.

Anyone have some sugestions?

thanks,
