Getting started with MQTT on Arduino and Python
Now that you have the Mosquitto broker installed on your computer, it means that you have a working broker that implements the MQTT protocol. Our next goal is to develop the MQTT clients in Arduino and also in Python so that they will work as publishers and subscribers. After implementing the MQTT clients, we will have a fully-functional MQTT system, where these clients communicate through the Mosquitto broker. Let's begin with deploying MQTT on the Arduino platform.
MQTT on Arduino using the PubSubClient library
As MQTT is a network-based messaging protocol, you will always need an Ethernet Shield to communicate with your network. For the following exercise, we will continue using the same hardware ...
