Arduino DDNS (Dynamic DNS) by Open-Electronics.org

This device captures the IP address of your network and it publish on site DynDNS.com. All without PC. It allow a remote access to your LAN even if the IP address of the connections changes. For logistics reasons the provider can not assign a IP fixed for all users, so many users, especially private, work with a dynamic IP or public IP: in practice when they connect modem or router, to their connection is a ...

Network-status indicator

I run a NFS/NIS network under a combination of OS's for the upper-division physics lab here at CSUC, and one source of irritation is when one machine goes down and nobody lets me know until suddenly that machine is absolutely necessary NOW! So I figured an Arduino, living in the machine on my desk, might serve as an early-warning system for network problems. I used red/green common-cathode LEDs for my indic ...

Tweetosapien: Hack a Robosapien With Arduino to React to Tweets

A really fun project sent into us by Thomas Meghe. He’s translated it all from his native French, which is a technical achievement itself. If you’d like to see the original, you can find it here. Bored of your favorite Twitter client ? No problem, here’s the solution ! In this post we are going to explain how to control the awesome WowWee Robosapien with a wirelessly connected Arduino to trigger some action ...

Pachube Client using Strings with Arduino

This example shows you how to answer a HTTP request using an Ethernet shield. Specifically, it connects to pachube.com, a free datalogging site. The example requires that you set up a pachube.com account, as well as a pachube feed (for more information on setting up an input feed, please click here). Your Ethernet shield will then connect to that feed and upload sensor data every 10 seconds. Additionally, t ...

Use your android phone sensors on the arduino

Hello, this is my very first step-by-step instructable, and today, we're going to learn how the sensors in your android smartphone can communicate with your arduino. In modern smartphones, there are a lot of useful sensors for an ingenious arduino project. I have a motorola DEFY, for example and it has (at least) 6 sensors : - light sensor - proximity sensor - aGPS (assisted gps) - compass/magnetometer - ac ...

How I’m building my bi-copter with Android and Arduino

Last year I was fascinated by the "How to build your own Quadrocopter" by Lenz Grimmer and decided that somehow I should try to do a similar thing. This talk is about the way I'm building a bi-copter using lessons learned for last year's talk and also with the errors I've made so far. My journey to getting a flying device running Multiwii is not yet complete. In this talk I will present all the common probl ...

Arduino Webserver Control Lights, Relays, Servos, etc…

In this project using only an Arduino with an Ethernet shield. I’ll be controlling one LED and a servo, but you can apply this method to control a DC motors, buzzers, relays, stepper motors, etc.. Overview: When you upload the the code provided in this tutorials. it creates a webserver in your LAN and you simply use the IP to access that webserver through your browser. After that it shows a webpage similar ...

3D Printed Webcam Controller

The camera controller box is an easy way to rotate a webcam from a PC or remotely through the internet. Step 1: Materials and 3D files In this project I used a Teensy 2.0 micro-controller since it was available, but you can use any other MCU like an ATtiny85 or an atmega328. The servo model number is S9001. I designed a place for a weight on the base part, in order to prevent vibrations and to keep the came ...

A World of Possibilities with Java ME + Bluetooth + Arduino

"This presentation shows how to easily go from user stories to automated integration tests that themselves read like user stories. You can accomplish this by using custom domain-specific languages. Too often our automated integration tests rely on coding and intimate technical knowledge of our systems, which not only limits who can write integration tests but also clouds our understanding of what the tests ...

A credit card sized Ethernet Arduino compatable controller board

I love the Arduino as a simple and accessible controller platform for many varied projects.  A few months ago, a purchased an Ethernet shield for my Arduino controller to work on some projects with a mate of mine - it was a massive hit - for the first time, I could control my projects remotely using simple software. That got me thinking - The Arduino costs about $30AUD, and the Ethernet board cost about $30 ...
