Learn how to connect Node-RED to a free public MQTT broker from EMQX to efficiently exchange data in your IoT and IIoT projects. In this step-by-step tutorial by PyLin, we'll guide you through the entire process, from broker setup to data publishing and subscribing.
Video Highlights:

🟢Introduction to EMQX Free Public MQTT Broker: Get to know the EMQX free public MQTT broker, including its IP address, hostname, and TCP port for connection.

🟢Setting Up Node-RED: Discover how to configure Node-RED to connect to the EMQX broker and set up data publishing and subscribing to any topic.

🟢Creating a Node-RED Flow: Follow along as we create a Node-RED flow using an inject node, an MQTT out node (publisher), and an MQTT in node (subscriber).

🟢Configuring Nodes: Learn how to configure the inject node to publish data, the MQTT out node to send data to the any topic, and the MQTT in node to subscribe to the same topic on the EMQX broker.

🟢Deploying and Testing the Flow: Watch the deployment of the flow and see the data published by the inject node being received by the MQTT in node.

🟢Using MQTT Explorer: Understand how to use MQTT Explorer software to subscribe to the any topic and receive data published from Node-RED.

🟢Bidirectional Communication: Learn about bidirectional MQTT communication, where you can also publish data from MQTT Explorer the MQTT Client Software to the EMQX broker.

By the end of this video, you'll be able to confidently use Node-RED and the EMQX public MQTT broker to create robust IoT and IIoT applications.
