/*
This example shows how to connect to Cayenne using an Ethernet W5100 shield 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. Set the Cayenne authentication info to match the authentication info from the Dashboard.
2. Compile and upload the sketch.
3. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
