Now you can use Arduino without wires! The Arduino BT board uses a Bluetooth serial connection in place of the USB connection found on the Arduino NG. This allows small wireless networks of boards to be built along with the ability to search for and communication with mobile phones. They feature an external range of up to 100m depending on its environment.

Designed for mobile use, the Arduino BT makes use of a DC-DC converter, allowing the board to be powered with a minimum of 1.2V, but with a maximum of 5.5V. Note: Higher Voltages or Reversed Polarity in the power supply are likely to Kill this Board!

Similar to the Arduino Mini, the Arduino BT uses a surface-mounted ATmega168. This doubles the available amount of storage space for your sketches, and adds three more PWM pins, and two more analogue inputs.

The Bluetooth Module used on this board is the Bluegiga WT11 (iWrap version). Further information & Data-sheets are available on the official Arduino BT page.

Configuration of the Bluetooth module is carried out with commands sent over the serial port from the ATmega168 (see the iWrap user’s guide for details).

The Name and pass-code of the Bluetooth module is set by running an initialization program on the Arduino BT. The default name of the Arduino BT is ARDUINOBT and the pass-code is 12345. Further details can be found in the initialization program’s source code.

As with all our Arduinos the ATmega168 chip comes preloaded with a boot-loader that allows you to upload your sketches to the Arduino BT via Bluetooth. (The source for the boot-loader is available within the Arduino SVN repository.)
