+
+  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.

+  Control a color gradient on NeoPixel strip using a slider!
+
+  For this example you need NeoPixel library:

+
+  App project setup:
+    Slider widget (0...500) on V1
