  • Don't power the board with more than 12 volts to the or reverse the polarity (power and ground pins) of your power supply, or you might kill the ATmega328 on the Arduino BT. Higher voltages or reversed polarity in the power supply can damage or destroy the board. The protection for reverse polarity connection is ONLY on the screw terminal. The Arduino BT can, however, run with a minimum of 2.5 volts, making it easier to power with batteries.

The Arduino BT is an Arduino board with built-in bluetooth module, allowing for wireless communication. This page explains how to get started using your Arduino BT. For more information on the board, see the Arduino BT hardware page.

Using the Arduino BT

To use the ArduinoBT, you'll need bluetooth connectivity for your computer. Many computers come with bluetooth connectivity, if yours doesn't, you'll need a bluetooth dongle.

First, you need to power the Arduino BT. The board takes a minimum of 1.2 volts and a maximum of 5.5 volts. If you apply more voltage or reverse the polarity of the power supply, you'll kill the board.

Second, you'll have to pair the Arduino BT with your computer. Search for bluetooth devices using your computer's bluetooth software. The Arduino BT will be called ARDUINOBT. The default pass code is 12345. You'll also need to create a virtual serial port (also called a virtual com port) for the Arduino BT. The steps required depend on your computer's bluetooth hardware and software.

Third, you'll need to set a couple of options within the Arduino environment. Select the virtual serial port corresponding to your Arduino BT from the Tools | Serial Port menu. Select ATmega168 from the Tools | Microcontroller (MCU) menu.

Now you should be able to upload a sketch to the Arduino BT. Open the led_blink example, reset the board, and press the upload button in the environment.

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:

  • First, pair the Arduino BT with your computer and create a virtual serial port for it.

  • Select ATmega168 from the Tools | Microcontroller (MCU) menu of the Arduino environment.
