bluetooth shield Bluetooth Expansion Board for Arduino
With this shield, Arduino device can be directly controlled from the pc or Bluetooth phone :
The Bluetooth Shield Bluetooth expansion board plugs directly into the Arduino main board , Arduino Bluetooth communication capabilities can be extended . Meanwhile, the expansion board is stackable , can stack other expansion board ( such as Ethernet expansion board , rocker panel extensions , key expansion boards, etc. ) on this basis , to achieve more.
The Bluetooth module along with master-slave function can be freely set by AT commands based on user needs , from the default mode , baud rate 9600 , matching 1234
