/* YourDuino.com Example: BlueTooth HC-05 Setup
 - WHAT IT DOES: 
   - Sets "Key" pin on HC-05 HIGH to enable command mode
   - THEN applies Vcc from 2 Arduino pins to start command mode
   - SHOULD see the HC-05 LED Blink SLOWLY: 2 seconds ON/OFF 
 
 Sends, Receives AT commands
   For Setup of HC-05 type BlueTooth Module
   NOTE: Set Serial Monitor to 'Both NL & CR' and '9600 Baud' at bottom right   
 - SEE the comments after "//" on each line below
 - CONNECTIONS:
   - GND
   - Pin 2 to HC-05 TXD
   - Pin 3 to HC-05 RXD
   - Pin 4 to HC-05 KEY
   - Pin 5+6 to HC-05 VCC for power control
 - V1.02 05/02/2015
