After a gentle introduction to the concept of IoT and what it entails, we take a dive into WebSockets and Asynchronous I/O in Python to explore other ways of controlling devices over a network. This post uses a simple two LED circuit to introduce WebSockets, and how to use them in Python together with the asyncio module.
The IoT revolution has started. But what is it exactly? Is it hard to take part to it? In this post I present you with all the details of a very simple and almost inexpensive Internet of Things project. Read through as we go from assembling the required hardware, to coding the software that will drive it, exploring some of the most modern free technologies that are on offer today. At the end we will be able to take control of some LEDs over the internet, from wherever we are. Consider this as a launch pad to more complex and exciting IoT projects.
