We will read a button and if it is pressed we will Toggle LED on Arduino side.Whereas, on Arduino we will use Adafruit MQTT library.

For this, we will create a Client object from paho-MQTT python package. The second step connects to the broker . In our case, we are running the broker on the same machine, therefore, we specify the broker’s IP as 127.0.0.1 and port as 1883 (default port for Mosquitto broker).
