) is received. Topics
are strings that act as filters for Messages and are hierarchical, meaning there are different levels. Remember, they are case sensitive.
In order to use this Node, the user must have already subscribed to the specified Topics
with the MQTT Subscribe Node.

The above image shows what happens when an MQTT connection has been made in the Project Settings. The connection's name will appear under Configuration
. One or more Topic Names
can be added, which appear as Output Pulses on the Node. It is possible to specify if they are binary or not. Each of these Topics
have a corresponding Body
String, which is the value in the MQTT key/value pair.
