Here's a link to one of my IoT students' project controlling some LEDs via a local MQTT broker.  
Although the project is over 3-years old it should still work.  
Hope it helps you get started with using MQTT as a transport medium.

> One of my IoT students was asking how to control a set of LEDs on a Wemos D1 Mini, that had been programmed using Arduino code, via MQTT commands from Node-RED. This is what the breadboard lash-up looks like... The red LED is connected to D8 (GPIO-15). The green LED is connected to D7 (GPIO-13) The yellow LED is connected to D6 (GPIO-12) This is the very simple test-flow we created in Node-RED.
