 | iot.received(String topic, String msg) | User-defined method that is called when the controller receives a message from one of the subscribed topics. The topic from which the message is received is the string "topic" and the body of the message is the string "msg".|
 | iot.publishMsgTo(String topic, String msg, bool retain) | Publishes the message "msg" to the topic "topic". Boolean retain informs the broker if the message should be saved into the memory of the broker.|

-===== Communication =====
+==== Communication ====
 The user can connect to and program this controller using the Distancelab environment.
-===== Limits =====
+==== Limits ====
 At the same time, one user can program the controller. But all users connected to the Distancelab MQTT broker can subscribe to and publish messages to the topics.
