// Blynk.App Quick Start
/*************************************************************
  This example shows how to use Arduino Ethernet shield (W5100)
  to connect your project to Blynk.

  NOTE: Pins 10, 11, 12 and 13 are reserved for Ethernet module.
        DON'T use them in your sketch directly!

  WARNING: If you have an SD card, you may need to disable it
        by setting pin 4 to HIGH. Read more here:
        https://www.arduino.cc/en/Main/ArduinoEthernetShield

  This is a simple demo of sending and receiving some data.
  Be sure to check out other examples!
