Getting Started with MQTT on Arduino Using ESP8266
Watch this video to learn how to use the Arduino IDE to program an ESP8266 microcontroller for reading sensor data and publishing it using MQTT to a HiveMQ Cloud MQTT broker.
Additionally, see how to receive MQTT messages as commands from the cloud and activate the microcontroller output to switch ON and OFF a Light Emitting Diode (LED).
