+/*
+  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 and Lora enabled boards supported by Arduino IoT Cloud.
+  On a LoRa board, if it is configuered 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 is compatible with:
+   - MKR 1000
+   - MKR WIFI 1010
+   - MKR GSM 1400
+   - MKR NB 1500
+   - MKR WAN 1300/1310
+   - Nano 33 IoT
+   - ESP 8266
