+This example shows how to connect to Cayenne using an Arduino Uno Wifi Rev2 and send/receive sample data.
+The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
+Steps:
+1. Install the Arduino megaAVR Boards from the Arduino IDE Boards Manager if you have not already done so.
+2. Install the WiFiNINA library.
+3. Select the Arduino Uno WiFi Rev2 board board from the Arduino IDE Tools menu.
+4. Set the Cayenne authentication info to match the authentication info from the Dashboard.
+5. Set the network name and password.
+6. Compile and upload the sketch.
+7. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
