Raspberry Pi GPIO pins the Python column

Over the last few columns, we’ve looked at some fundamental concepts in Python, concerning objects, object- oriented programming and how objects are stored in memory. This issue, let’s take a look at the Raspberry Pi and one of the unique features not usually offered on single-board computers. Of course, I’m speaking of the GPIO pins. GPIO stands for general-purpose input/ output. The pins provide an interface between the Raspberry Pi and the outside world. They can act as either inputs into the computer, or outputs to the world. With the addition of these pins, the possibilities for the Raspberry Pi explode. It goes from being simply a single-board computer to a project platform.
