+/* FILE:    ARD_BLUETOOTH_SERIAL_MODULE_HCARDU0004_Example.pde
+   DATE:    17/07/12
+   VERSION: 0.2
+
+  REVISIONS:
+  
+  27/08/12> V0.2 updated software serial functions as these are now included 
+            with V1.0 of the Arduino development environment.
+
+This is a simple example of how to use the HobbyComponents Bluetooth serial 
+module (HCARDU0004). This module allows communication from an Arduino dev 
+board to a Bluetooth enabled device. The module communicates with an Arduino 
+device via a simple two wire serial protocol. If you choose to use the modules 
+default settings then the module requires no setting up to communicate with it,
+just connect to the Arduino. The device defaults to 9600 baud, 8 data bits, 
+and 1 stop bit. The baud rate, amongst other settings can be changed using 
+standard AT commands via its serial interface.
+
+This sketch demonstrates an example of how to communicate with the 
+device using a software serial interface using just two DIO lines to interface 
+with the module. The program will pass-through for any data sent to and from 
+the device to the Arduino's hardware serial interface. This will allow you to 
+communicate with any device paired with the module via Arduino IDE's built in 
+serial port monitor.
+
+
+SENSOR PINOUT:
+
+PIN 1: KEY
+PIN 2: VCC
+PIN 3: GND
+PIN 4: TXD
+PIN 5: RXD
+
+
+SETUP INSTRUCTIONS:
+
+Connect the Bluetooth module as follows:
+
+Arduino       Bluetooth module
+5V            PIN 2 (VCC),
+GND           PIN 3 (GND)
+DIO 10        PIN 4 (TXD)
+DIO 11        PIN 5 (RXD)
+
+Compile the sketch and upload to your Arduino. 
+
+Pair your Bluetooth enabled device with the Bluetooth module using PASSCODE: 1234
+(you do not need to do anything on the module side to do this).
+
+Open up the serial port monitor in the Arduino IDE (CTRL+SHIF+M).
+
+You will now be able to communicate with the paired Bluetooth device.
+
+
+You may copy, alter and reuse this code in any way you like but please leave 
+reference to HobbyComponents.com in your comments if you redistribute this code.
