  Blynk is a platform with iOS and Android apps to control
  ESP32, Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build mobile and web interfaces for any
  projects by simply dragging and dropping widgets.

  This example code is in public domain.

 *************************************************************
  This example runs directly on ESP32 chip.

  NOTE: This requires ESP32 support package:
    https://github.com/espressif/arduino-esp32

  Please be sure to select the right ESP32 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!
