Operating a Simple Switch and LED on the Raspberry Pi. GPIO, as may have been explained in other tutorials, stands for General Purpose Input/Output and a In this tutorial we'll show two different approaches to reading and driving the Raspberry Pi's GPIO pins: python and C. Here's a quick overview of what's covered:. Hello and welcome to part 6 of the Raspberry Pi tutorial series. In this tutorial, we're going to be introducing and using the GPIO (General Purpose Input Output) 28 Feb 2014 The GPIO pins on a Raspberry Pi are a great way to interface physical devices like buttons and LEDs with the little Linux processor.9 Sep 2015 One of the biggest selling points of the Raspberry Pi is its GPIO, or General Purpose Input/Output ports. They are the little pins sticking out of the circuit board and allow you to plug various devices into your Raspberry Pi. With a little programming, you can then control them or detect what they are doing. 5 Jun 2018 The Raspberry Pi is a Linux computer. But unlike most desktop and laptop Linux computers, users have access to a row of pins which can be used as inputs or outputs. These 40 pins are called GPIO (General Purpose Input Output) pins. This Raspberry Pi GPIO tutorial aims to help you program these pins for your purpose. 9 Sep 2015 In this Raspberry Pi GPIO tutorial, we are going to take a look at all the basics of the GPIO pins or also know as the general purpose input and GPIO. A powerful feature of the Raspberry Pi is the row of GPIO (general-purpose input/output) pins along the top edge of the board. A 40-pin GPIO header is On the first two models of Raspberry Pi, there were only 26 pins, but it quick. GPIO stands for General Purpose Input-Output, what this means in layman terms is that the the pins can be used as either inputs, . Products used in this tutorial.
