NOTE: This is a 3.3V Shield, Only Use it with a 3.3V Arduino Variant!
Tutorial Can Be Found HERE.
Bluetooth Shield, a serial port Bluetooth module (Master/Slave) breakout board. You can choose ARDUINO's Digital PIN D0->D7 as Software UART to communicate with Bluetooth Shield(and D0,D1 also is Hardware UART).
Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR(Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore 04-External single chip Bluetooth system with CMOS technology and with AFH(Adaptive Frequency Hopping Feature). Hope it will simplify your overall design/development cycle.
And now, we provide HC-05, which could be set to Master or Slave by user.
