Explore this tutorial demonstrating how the Arduino Yún can be controlled from anywhere with any internet connected web browser. The solution is provided by Bo Peterson using the Yaler service which means that the Yún can be reached from any network without knowing the IP-address, and without any port forwarding on the router where the Yún is connected.
A common problem in home automation and internet of things applications is that it is difficult to reach devices connected behind wifi routers from the outside. There are different approaches to overcome this problem:
- Port forwarding and static ip addresses. This solution requires the user of the connected device to know how to configure a router and have access to router administration which is not always possible. A Yun tutorial with port forwarding is found here.
- Polling is a technique where the connected device at regular intervals checks with an external server if the device should take action. This solution requires no configuration of the router but it creates extra network traffic and response delays.
- A third way is to use WebSockets which is a way of providing real time full-duplex communication over TCP. Spacebrew is a good open source toolkit for connected devices using WebSockets. Autobahn is another infrastructure that can be used.
- Reverse HTTP is the solution that will be used in this tutorial. We will use Yaler which is an open source relay infrastructure that gives access to connected devices with very little configuration.

It’s FIFA World Cup time and we have a project for makers who prefer to be active instead of only watching the others play. The exciting penalty shoot-out we’ve always enjoyed in video games was implemented by Germán Carrillo as an electro-mechanical game where you save goals using a control device and kick the ball with your fingers:

At the end of May, Massimo Banzi and Giorgio Olivero (Todo) spent some days at the Copenhagen Institute of Interaction Design to teach a class called Connected Objects. The class goal was to envision, design and implement interactive objects that are open and connected, whose design and behaviour can be used to sense, read and affect the domestic landscape or other shared environments.
One of the team of students (Arun Mota, Hsiang-Lin Yang, Yashodeep Gholap) worked on Arduino Yún to create an energy redistribution service that allows people to save money and in parallel donate towards energy distribution projects in deprived areas of the world:
LightUp is an interactive fundraising coin jar that firstly encourages personal savings and then also allows people to contribute a part of their savings towards the cause. The system allows them to track in real-time exactly how many units of electricity they helped generate. Another visible reward is the jar lights up for 10 minutes each time they drop a coin.

Glaciers are the largest moving objects on earth and the glacier on the Austria’s sixth highest summit called Simulaun is the protagonist of an installation awarded a Special Mention by the Jury of the 14th International Architecture Exhibition of La Biennale di Venezia.
On May 4th, 2014, the Italian Limes team installed a network of solar-powered GPS units on the surface of the Similaun glacier, following a 1-km-long section of the border between Italy and Austria, in order to monitor the movements of the ice sheet throughout the duration of the exhibition at the Corderie dell’Arsenale.

It’s time to announce a new partner in the Arduino At Heart program!
Nix, The Diamond Standard In Color Measurement, is a unique device capable of determining the exact color of any object or surface in RGB, CMYK, HTML, Lab, and even specific paint from your favorite brand. Imagine a Photoshop eyedropper in real life: Nix is a small, durable, buttonless tool that can easily fit in your pocket or bag.
It’s a useful device especially for graphic designers, interior designers, artists, photographers, hobbyists, anyone who wants to become a colour expert. It utilizes Bluetooth 4.0 technology to display the exact color on your iOS or Android device. Once scanned, you can keep palettes of your favorite colors, match the color to real life pigments, and even receive directions to the nearest store where you can purchase the color.
On top of that Nix is ultra hackable. You can easily reprogram it with all the familiar tools available in the Arduino IDE.
Take a look at their successful kickstarter campaign page and at the video below to learn more :
Nix Color Sensor is designed and assembled in Hamilton, Ontario, Canada by Nix Sensor Ltd and its CEO Matt Sheridan (email@example.com) is available to answer all your questions. If you want to make it yours, visit the webesite nixsensor.com .

Our friends at Temboo are releasing more cool stuff for your Internet of Everything. Here’s some news from their blog.
Now you can connect even more Arduinos with the power of Temboo by simply flipping our IoT Mode on. This new feature opens up a whole new world of possibilities for the Internet of Things.
What is IoT mode, you ask?
It’s a new way to access our 2,000+ Choreos on any of your Arduino or Arduino-compatible boards. By just hitting a switch at the top right of any Choreo page, you “got the power” to call that Choreo with a sketch tailored specifically for the device you pick from our drop down menu. Previously, this feature was only available for the Yún, but now it is open to the larger Arduino family. All you have to do is select the type of shield your board uses and the code will generate accordingly.
So how do I begin using this amazing IoT feature?
Select a Choreo from our vast Library and turn on IoT Mode. In the example above, we chose the Data.gov API and the GetCensusIdByCoordinates Choreo. Data.gov is a cool way to access APIs from a number of US governmet agencies and to query government datasets, including the US Census! Read the rest of this entry »

We’re happy to share with you the update of the Indiegogo campaign of the Arduino At Heart for home automation we presented some time ago. Ez Control goes wireless!
We have been silent for most of the time of this campaign, but this doesn’t means that we were sleeping. Not at all!
We were listening and interacting. We have received your comments, we have followed the topic on Reddit, we have exchanged ideas with many of you and we spent all this time improving our product.
Some of you was concerned about the relay, maybe too small. Some other concern was related to the position of the temperature sensor, that could offer false reading caused by the heat from other components.
We have upgraded the relay with a new one, rated 5A, and we have also improved the physical insulation for the high voltage circuit. We have then improved the insulation of the temperature sensor. Read the rest of this entry »

The MakerFaire Rome Call for Makers runs until June the 15th, so you should be quick as we are only a couple of days away from final deadline!
If you’ve got an awesome project you want to show off to thousands of people in the capital of Italy, this is your moment.
The Call for Makers originally was due to close on the 25th of May, but we knew you needed some extra time to finalise your project, and we’ve extended it to next Sunday, June the 15ht, 2014 at midnight (CEST) and this is the final last call.
You can submit your project right now on this page and let us know it via Twitter, Facebook and Instagram using the hashtags #Call4Makers and #MFR14.
