Please check out the detailed tutorial on the same Getting Started with MQTT on Arduino Using NodeMCU ESP8266 - HiveMQ

This tutorial shows you how to use the Arduino IDE to program an ESP8266 microcontroller to read sensor data and publish it using MQTT to a HiveMQ Cloud MQTT broker. It also shows you 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).
