-  This sketch demonstrates how to exchange data between your board and the Arduino IoT Cloud.
-
-  * 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 WiFi, GSM, NB, Ethernet and Lora enabled boards supported by Arduino IoT Cloud.
-  On a LoRa board, if it is configured as a class A device (default and preferred option),
-  values from Cloud dashboard are received only after a value is sent to Cloud.
+  This sketch demonstrates how to connect to ArduinoIoTCloud and AWS IoT core.
