  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.

 *************************************************************

  Blynk can provide your device with time data, like an RTC.
  Please note that the accuracy of this method is up to several seconds.

  App project setup:
    RTC widget (no pin required)
    Value Display widget on V1
    Value Display widget on V2

  WARNING :
  For this example you'll need Time keeping library:
    https://github.com/PaulStoffregen/Time

  This code is based on an example from the Time library:
    https://github.com/PaulStoffregen/Time/blob/master/examples/TimeSerial/TimeSerial.ino
