Some of us believe greater can be fulfilled when technology upbuilds and completes the great, prior products of our efforts. It’s the basic fundamentals how all of us evolved. GPIO I’ve experienced is in a way a shortcut that trims down to the simple core functions it was originally meant to do. I can build …

If you want to build electronic devices, at some point you’re going to need to read data through GPIO. In this exercise, we’re going to read the value of a push button on a breadboard. Set up the circuit as shown in the pictures on the right. Note that one end of the 4.7kOhm resistor …

One powerful feature of the Raspberry Pi is the row of GPIO (general purpose input/output) pins along the edge of the board, next to the yellow video out socket. These pins are a physical interface between the Pi and the outside world. At the simplest level, you can think of them as switches that you …

This video explains how to connect LEDs to a Raspberry Pi’s general purpose input-output (GPIO) pins, and how to write Python code to turn them on and off. This video shows how to construct a Pololu Zumo robot chassis, how interface it to a Raspberry Pi using an L298N H-bridge motor controller, and how to …
This is the second section of the raspberry pi weather station project. How to set up the Raspbian operating system and proxy settings are included in the section one. The main concern in section two is to give an idea about the General Purpose Input / Output ports (GPIO) in Raspberry pi. This section consists …
Raspberry PI weather station – Section two – GPIO Continue Reading
I had heard about GPIO pins on the raspberry pi and decided to do something with it. And with the holidays coming, wouldn’t it be great to be able to turn on and off your light display from the web! This is a pretty simple project that creates a web app for controlling lights. It uses the …
In this post I will take you through the fairly simple task of getting your Raspberry PI to control an LED via the GPIO interface, the task is simple however it lays a great foundation of knowledge for any further projects where you want to interface with an external electronic device. So the first step is to …
How To: Control LED using Raspberry PI GPIO Continue Reading
This will be the easiest Raspberry Pi GPIO LED project ever. If you follow this guide it should take less than 20 minutes to setup and have running. The goal of this project is to get a single LED light blinking based on a Python program running on a Raspberry Pi. In order to do …
Presumably everyone knows what the Raspberry Pi is, by now, so I’ll not start there. You may or may not know that the RasPi has General Purpose Input/Output (GPIO) pins as standard. Some of these provide 3.3v power, some provide 5v power, some are grounded and the others can be used for input and output. …

This tutorial covers the setup software and hardware to read and write the GPIO pins on a Raspberry Pi running the latest Raspbian operating system. We will showing how to read from a physical push-button from Python code, and control an LED. Related categories: Tutorial Step 1: Install Python development tools Open a terminal on …
