MQTT clients are very small, require minimal resources so it can be used on small microcontrollers like ESP8266 or ESP32 etc for different IoT projects. During the video, I have explained in details what is MQTT client and MQTT broker, how the MQTT protocol works, how to use MQTT in building automation projects. Also shown how to install the pubsubclient library and program ESP8266 NodeMCU with Arduino IDE. After watching the complete MQTT tutorial video, you can easily make this MQTT home automation project with your own MQTT server.
