+  Blynk is a platform with iOS and Android apps to control
+  ESP32, Arduino, Raspberry Pi and the likes over the Internet.
+  You can easily build mobile and web interfaces for any
+  projects by simply dragging and dropping widgets.

+ *************************************************************
+  This example shows how to configure static IP with Ethernet.
+  Be sure to check ordinary Ethernet example first!!!
+
+  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
+
+  Feel free to apply it to any other example. It's simple!
