[Note: in the following sample code, the soft serial has a baud rate of 38400, which makes the code a little bit not stable, if you see failure, please try multiple times].

• Take one Bluetooth shield and do the following:

Select the Bluetooth shield communication port using jumpers: BT_RX is connected to D6 of Digital-6, BT_TX is connected to Digital-7. Move the mode selection switch to lower position so that Bluetooth module will enter into AT command mode.

Install Bluetooth shield on the Arduino Uno,and plung Arduino into PC, LED D1 on Bluetooth shield will start blinking.Copy and paste the following sample code and download to Arduino: #include #define RxD 7 #define TxD 6 SoftwareSerial BlueToothSeria
