/* Virtuino example  (Bluetooth)
 * Example name = "Read temperatures from two ds18b20 sensors "
 * Created by Ilias Lamprou
 * Updated 24 02 2017
 * This is the code you need to run on your arduino board to cummunicate whith VirtUino app via bluetooth
 * Before  running this code config the settings below as the instructions on the right
 *
 * Download latest Virtuino android app from the link: https://play.google.com/store/apps/details?id=com.virtuino_automations.virtuino

/*========= VirtuinoBluetooth Class methods
*  vPinMode(int pin, int state)                                  set pin as digital OUTPUT or digital INPUT.  (Insteed default pinMode method
*
*========= Virtuino General methods
*  void vDigitalMemoryWrite(int digitalMemoryIndex, int value)   write a value to a Virtuino digital memory   (digitalMemoryIndex=0..31, value range = 0 or 1)
*  int  vDigitalMemoryRead(int digitalMemoryIndex)               read  the value of a Virtuino digital memory (digitalMemoryIndex=0..31, returned value range = 0 or 1)
*  void vMemoryWrite(int analogMemoryIndex, float value)         write a value to Virtuino float memory       (memoryIndex=0..31, value range as float value)
*  float vMemoryRead(int analogMemoryIndex)                      read the value of  Virtuino analog memory    (analogMemoryIndex=0..31, returned value range = 0..1023)
*  run()                                                         neccesary command to communicate with Virtuino android app  (on start of void loop)
*  void vDelay(long milliseconds);                               Pauses the program (without block communication) for the amount of time (in miliseconds) specified as parameter
*  int getPinValue(int pin)                                      read the value of a Pin. Usefull for PWM pins
