The Arduino BT is an Arduino board with built-in bluetooth module, allowing for wireless communication. To get started with the Arduino BT, follow the directions for the Arduino NG on your operating system (Windows, Mac OS X, Linux), with the following modifications:
In most respects, the Arduino BT is similar to the Arduino Diecimila. Here are the main differences of BT board (besides the fact that it communicates over bluetooth instead of USB):
For more details, see the Arduino BT hardware page.
The on-board serial communication between the bluetooth module and the Arduino sketch (running on the ATmega168) needs to be at 115200 baud (i.e. call Serial.begin(115200) in your setup() function). Communication between the bluetooth module and the computer can be at any baud rate.
Communication between the BT module and the computer can be temperamental. You might want to open the serial monitor a couple of seconds after resetting the board.
