// Basic bluetooth test sketch. HC-06_01_9600
// HC-06 ZS-040 
// 
// 
//  Uses hardware serial to talk to the host computer and software serial for communication with the bluetooth module
//
//  Pins
//  BT VCC to Arduino 5V out. 
//  BT GND to GND
//  BT RX to Arduino pin 3 (through a voltage divider)
//  BT TX to Arduino pin 2 (no need voltage divider)
//
//  When a command is entered in the serial monitor on the computer 
//  the Arduino will relay it to the bluetooth module and display the result.
//
//  These HC-06 modules require capital letters and no line ending
//
