 * You can easily build graphic interfaces for all your
 * projects by simply dragging and dropping widgets.

 **************************************************************
 * This example runs directly on ESP8266 chip.
 * You need to install this for ESP8266 development:
 *   https://github.com/esp8266/Arduino
 * Please be sure to select the right ESP8266 module
 * in the Tools -> Board menu!
 *
 * Change WiFi ssid, pass, and Blynk auth token to run :)
 * This is Blynk's basic ESP8266 sketch, modified by Costas
 * to include a few other essential items 9th Sept 2016.
 * 
 * We recommend you download DroidX to your PC and run Android
 * via this simulator, direct D/L link http://dl.haima.me/download/DXDown/win/Z001/Droid4XInstaller.exe
