  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.

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

  You can synchronize the state of widgets with hardware states,
  even if hardware resets or looses connection temporarily

  Project setup in the Blynk app:
    Slider widget (0...1024) on V0
    Value display (0...1024) on V2
    Button widget on digital pin (connected to an LED)
