In this tutorial, we’re going to show you how to create a simple state machine using PubNub Functions; however, before we do so, let’s explain what a state machine is and their importance.What is a State Machine?First and foremost, a state machine is a mathematical abstraction that allows a device to be in one of a set number of stable conditions, depending on its previous condition and on the present values of its inputs. A stoplight is an example of a state machine, changing its state to green, yellow, or red, depending on whether there is a car present or not.State machines are a fundamental tool in computer programming and are highly effective infrastructures for embedded devices, especially within the IoT domain. As most IoT devices are put into situations where they are gathering (...)
