Steve’s Guide to MQTT, Node-Red and Mosquitto

Hi and Welcome to Steve’s Internet Guide.beginners guide internet-and-networking

The first wave of the Internet involved connecting people to each other and people to information.

The next wave of the Internet will involve connecting the physical world to the Internet, and machines to each other (M2M – Machine to machine).

Every object, both real and virtual, connected to, and accessible over the Internet is the basic idea of the Internet of Things or the internet of Everything.. See- Beginners Guide to IOT

Although the Internet of Things will make use of the existing Internet and Internet technologies t will introduce new technologies and services.

This site is currently focused on the MQTT protocol which looks like becoming the main protocol for IOT projects.

Software will play an important role in the IOT and I will also cover Node-Red,node.js and Python.
