*    @description of the program: 
*    
*    This is a very basic bluetooth program which sends data (a number in this case) 
*    through bluetooth module to a PC or smart phone (simply any device which has 
*    bluetooth connectivity) and increments the number every 500 ms and writes it 
*    to the screen with the regular printf function.
*
*    @connections:
*-------------------------------------------------------------- 
*    |LPC1768|        |Peripherals|
*    Pin 13 --------> (TX) RX pin of the Bluetooth module 
*    Pin 14 --------> (RX) TX pin of the Bluetooth  module
*    GND ----------->  GND of the Bluetooth module
*    VOUT (3.3 V) -->  VCC of the Bluetooth module
*---------------------------------------------------------------
