The Arduino Bluetooth is the very popular Arduino board featuring a build-in Bluetooth module. The serial connection to your PC is made over Bluetooth instead of USB. This is Arduino in true wireless fashion: no wires even when programming it!
Arduino Bluetooth - True Wireless Connection!
The Arduino Bluetooth is based on the Atmega168 and the Bluegiga WT11 module (iWrap version). Serial communication is done wirelessly, including programming the microcontroller.
The Bluegiga WT11 module allows for Bluetooth communication with computers, phones and other devices. It communicates with the microcontroller via serial and should be detectable by the operating system's Bluetooth drivers, which provide a virtual COM port that is then used by the IDE. The serial monitor uses this same connection to send simple textual data to and from the board.
The Arduino Bluetooth operates on a minimum of 1.2 volts, making it easy to run it using batteries.
Input and Output
- 14 digital pins that can be used as input or output. Each pin operates at 5 Volts and can provide or receive a maximum of 40 mA.
- 6 analog pins that can be used as input, providing 10 bits of resolution (1024 different values). They measure from 0 to 5 V by default but it is possible to reconfigure the upper end of this range using the AREF pin (and low-level code).
