/*************************************************************
Download latest Blynk library here:
https://github.com/blynkkk/blynk-library/releases/latest
Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.
Downloads, docs, tutorials: http://www.blynk.cc
Sketch generator: http://examples.blynk.cc

This example code is in public domain.
*************************************************************
This example shows you how you can use server as storage for
your data like EEPROM
Project setup in the Blynk app (not necessary):
Value display on V1 in PUSH mode.
