   Description:
        A Simple bluetooth app which demonstrates how to connect
        smartphone + HC06 + using arduino + MIT App Inventor 2.
        The application uses TWO sliders to change the LED's  
        brightness.
   MCU:       Arduino 1.6.12 - @16MHz       http://www.arduino.cc/
   IC Chip:   Bluetooth Datasheet - HC-06   https://goo.gl/s9ZcNC
   Connections:
   See Official youtube channel vid: https://youtu.be/ze7X0j8DtBA
   Based on:   Control 5 leds using arduino and app inventor.
