The Arduino Blue Tooth

The Arduino Blue Tooth is a microcontroller board based on the ATmega168  and the Bluegiga WT11 bluetooth module . It supports wireless serial communication over bluetooth (but is not compatible with Bluetooth headsets or other audio devices). It has 14 digital input/output pins (of which 6 can be used as PWM outputs and one can be used to reset the WT11 module), 6 analog inputs, a 16 MHz crystal oscillator, screw terminals for power, an ICSP header, and a reset button. It contains everything needed to support the microcontroller and can be programmed wirelessly over the Bluetooth connection. Instructions are available for getting started with the Arduino BT.

Specifications:

  • Microcontroller ATmega168
  • Operating Voltage 5V
  • Input Voltage 1.2-5.5 V
  • Digital I/O Pins 14 (of which 6 provide PWM output)
  • Analog Input Pins 6
  • DC Current per I/O Pin 40 mA
  • DC Current for 3.3V Pin 50 mA
  • Flash Memory 16 KB (of which 2 KB used by bootloader)
  • SRAM 1 KB
  • EEPROM 512 bytes
  • Clock Speed 16 MHz
