Step 1 - Wiring diagram

Unplug the bluetooth module before you upload the sketch to your Arduino board, then plug it back in right after, or you might experience communication problems between your computer and the Arduino

To get the temperature on your android device, install Bluetooth Terminal App ( from Qwerty as i recall). Once you're connected, sending the A letter enables you to get the temperature back.
