Introduction Icon.png Introduction

The great thing about the IoT is it is a whole network of things – there are many different types of devices which are now IoT enabled, from 3D printers to mass storage devices, and from WiFi kettles to autonomous delivery robots.

Not all hardware is useful for all purposes, however, and sometimes things may be IoT enabled for the sake of it or as a gimmick, rather than to add useful functionality. In this topic you will look at some of the additional hardware that may be used in IoT, and both the advantages and disadvantages of them.
