The Internet of Things , a term being bandied to the point of almost meaninglessness now it’s hit the mainstream of the NYT and the BBC . Yet, while the mainstay of the media struggles to describe how and why smart sensor arrays are going to mean you spend less time in traffic, ultimately pay more for your electricity but make sure your fruit is always fresh, there is a quiet revolution taking place. The action taking place is the creation of what I call the Sensor Commons. Why is this a revolution? Because as a population we are deciding that governments and civic planners no longer have the ability to provide meaningful information at a local level.

This is the start page for my series of over fifty Arduino tutorials . Each tutorial from chapter zero to thirteen will cover a variety of topics and lessons, then from chapter fourteen each chapter will cover a particular topic. If you are looking to learn about the world of Arduino – this is a great place for beginners to start, or for more experienced users to brush up on their knowledge. Scroll down to read the contents of each chapter. New tutorials, lessons and other articles of interest are announced via twitter , Google+ , RSS feed and by email – to keep up, subscribe using the form in the column to the right.

Were you ever the kind of person to hack up your own Playstation controllers and hook it up to something else? Well, those shards of plastic can be mighty dangerous, so I’ve done it for you. And hey, with the GamePack you’ll even have something you can hook it up to. The GamePack comes with an Arduino, MeCap Backpack, TouchShield Stealth or Slide, ExtenderShield and an InputShield- everything you need to create your own open source, portable gaming device.

xoscillo - A software oscilloscope that acquires data using an arduino or a parallax (more platforms to come).
About This is a multiplatform software oscilloscope and logical analyzer. It supports arduino(with custom firmware) and a Parallax USB oscilloscope . More platforms to come.
HMC5883L Compass Tutorial with Arduino Library - Tutorials - Love Electronics
Using a magnetometer can be a little tricky, especially if your unsure about the formulas to use to get the correct bearing and when other magnetic objects are interfering with your signal. We've created a library for our HMC5883L Breakout Board , which will also be compatible with other HMC5883L breakout boards made by other manufacturers. Join us whilst we cover the following: Understand what is a magnetometer and how they work. Introduce the HMC5883L Arduino Library Explain how to extract data from the HMC5883L.In conjunction with the release of the new Arduino PID Library I’ve decided to release this series of posts. The last library, while solid, didn’t really come with any code explanation. This time around the plan is to explain in great detail why the code is the way it is.
Improving the Beginner’s PID – Introduction « Project Blog
Ah yes… the wonderful and oft-misunderstood world of microcontroller interrupts. Are you looking to build a project that relies on very precise timing or needs to react quickly to an input? Then don’t change that channel, my friend. In this tutorial we’ll cover what interrupts are, what they do, and how to use them.
