The Arduino Yún is a WLAN capable development board featuring an ATMega microcontroller, as well as a separate chip running a small Linux distribution, making it a perfect candidate for home automation projects like in the picture below! This basic tutorial will show you how to communicate wirelessly between your Arduino Yún and an Android

Control the position of a RC (hobby) servo motor with your Arduino and a potentiometer. This example makes use of the Arduino servo library. Hardware Required Arduino Board (1) Servo Motor (1) Potentiometer hook-up wire Circuit Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected
I’ve been slowly working on this project for the past month or so. I finally have some time to share and post-up what I’m working on. I know there are commercial products available, but then what’s the fun in that! What I want is a Fully Automated LED Primary Lighting System which can control separate

The idea behind this project was very straightforward: design an inexpensive remotely controlled system capable of taking still pictures and uploading them to a remote file storage with a camera to be activated by either remote commands or sensor events. And after numerous brain storms the following solution has been found.In base configuration the system

In our last episode, I explained how I redesigned the controller from what I first thought I was going to do. Now, I am going to explain how to make your own thermal differential controller based on mine. As it is, this setup will only control an AC load, but it would be fairly simple

A few weeks ago, it came to my attention that IKEA do a set of colour-changeable LED strips. I’ve been looking for a decent way of providing some lighting behind my computer to reduce eye-strain for a long time, and these seemed perfect: I was very pleased with them, but no self-respecting nerd would stop

Introduction Ghosty is an autonomous little robot who is adventurous and loves to explore his surroundings. However, unlike a normal ghost, he doesn’t like to scare people. Instead they actually scare him! In our most current version of Ghosty, his vision line is based on the data of two proximity sensor data reads. The difference

Here’s the Arduino version of a project to use the General Instruments (GI) SP0256-AL2 vintage speech synthesis chip to say “hello world”. I’d previously shown how to do this with a Basic Stamp 2. Here’s what it sounds like saying, “hello world” 20101215_164333.mp3 How it works, in short, is that the GI chip must be
