Connect a device to the Cayenne dashboard using MQTT.
The Cayenne MQTT Arduino Library provides functions to easily connect to the Cayenne IoT project builder. This library bundles the Eclipse Paho MQTT C/C++ client library for MQTT support. http://www.cayenne-mydevices.com/
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
