+  This sketch demonstrates how to use Arduino IoT Cloud without ArduinoConnectionHandler
+
+  * Connect a potentiometer (or other analog sensor) to A0.
+  * When the potentiometer (or sensor) value changes the data is sent to the Cloud.
+  * When you flip the switch in the Cloud dashboard the onboard LED lights gets turned ON or OFF.
+
+  IMPORTANT:
+  This sketch works with only with WiFi.
