I’ve been fascinated with LED cubes for a while now, but haven’t been able to bring myself to build an Arduino-based cube. They turn on quickly and nicely, yes, but writing the code is a horrible mess of bits and bytes. The Raspberry Pi’s Python-based GPIO interface was much more appealing (and readable) to me,

Hi, in this instructable, I’ll show you how to create a lightweight and incredibly responsive web server with WebSockets. I’ll use it to control a LED using an Arduino but the concept can be applied to many other projects. Since this project does not use any on-board peripherals, it will work with just about any

The General Purpose Input/Output pins (GPIO) give you power to interact with the real world using your Raspberry Pi. This project will get you comfortable with using the GPIO pins, which will form the backbone of the final project. Traditionally the ‘Hello World’ program for electronics prototyping is simply turning a light on and off.

Moving on from “My first GPIO LED”, I decided to take a look at a different LED I had in my possession, an L-59BL/1. This LED has 3 pins and I had no idea what they were for, so I Googled it and found this parts list, and this data sheet. So this LED has

A couple weeks ago my Dad mentioned to me it would be cool if advent candles automatically lit themselves according to the date. (One candle is lit starting the 4th Sunday before Christmas with an additional candle being lit for each of following Sundays). I thought, hey, that sounds like an interesting project, so why

In part 1 of this series, we looked at the basic commands for using software pulse-width modulation (PWM) in RPi.GPIO 0.5.2a and higher. In this article we’ll get a bit more hands-on and into some practical applications for it. It’s all very well being able to make nice square-wave pulses on an oscilloscope, but what’s

In this instructable I’ll show you how you can build your own LED Rubik’s cube. This project was done for an introductory electronics course at Pomona College. Groups were given approximately two months to complete a project of their choosing, the only requirement being that the project rely on electronics built by the students. Our
