*************************************************************
This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:
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 :)
Feel free to apply it to any other example. It's simple!
