We will use Python on the server side and I will use LED to make it easier to understand ,"If you can control LED you can control everything". I spent a little time researching four different methods of Raspberry Pi GPIO manipulation in C. Here are two simple programs testing the performance of my rpio library against popular alternatives which use the /sys interface (with the number of npm stars indicated for a rough idea of popularity). By the end of this tutorial, you will have a Raspberry Pi that runs a Python program that will turn two sets of LEDs on and off in an infinite loop.
