+  Program Operation - This is a simple program to test a Serial Bluetooth device is working. The program 
+  uses software serial to send a Hello World message to a serial port. If the Bluetooth device is paired
+  with an Android device you should see Hello World in an Andriod Bluetooth terminal application. 
+
+  Bluetooth baud rate is set at 9600, an HC-06 Bluetooth device is assumed. 
+  Note that not all pins on all Arduinos will work with software serial, see here;
+
+  https://www.arduino.cc/en/Reference/softwareSerial
+
+  Serial monitor baud rate is set at 115200.
