    Upgrading the OpenWrt-Yun image on the Yún


    Today we released the upgraded version of the OpenWrt-Yun image on the Arduino Yún.
    This version includes all the latest and greatest from stable OpenWrt, the latest (Python) Bridge (with a php contribution and fixes to the file module), we also added Mailbox support to REST api and other fixes to some open issues.

    The new image contains also the fix to the well known Heartbleed bug, a big security issue that impacted on almost all websites of the world.

    If you own an Arduino Yún we suggest you to follow the link and read the procedure to update the board.
    You’ll need to download the zip file from the download page. Remember that updating the OpenWrt-Yun image will cause the loss of all files and configurations you previously saved on the flash memory of the Yún.

    MakerFaire Rome: the european call for makers is online! Join us

    Maker Faire 2014


    It’s time to start tinkering on new projects or pimp-up some old ones because MakerFaire Rome is calling!

    Last year it was an overwhelming experience for all of us: more than 35.000 people from all over the world gathered for the first edition of the European edition of MakerFaire. Around 24o makers presented their projects ( 60% from Italy and 40% from the rest of the continent) and showed to a crowd of enthusiasts and newbies  the impact of open source community and DIY on our lives.

    If you want to join us with your project in Rome from the 3rd to the 5th of October, take a look at the Call for Makers and fill it before the 25th of May:

    The first step to participate in Maker Faire Rome as Maker is to submit an entry that tells us about yourself and your project. Entries can be submitted from individuals as well as from groups.
    Please provide a description of what you make and what you would like to bring to Maker Faire, including links to photographs and/or videos of your project. We particularly encourage exhibits that are interactive and that highlight the process of making things. Continue >>

    How to make your own Primo prototype using digital fabrication and Arduino boards

    primo doc

    Primo‘s team sent us exciting news from their HQ about their contribution to the open source community. After the successful Kickstarter campaign to launch the wooden play-set that uses shapes, colours and spacial awareness to teach programming logic through a tactile, warm and magical learning experience, they took a step further. They released all the documentation and the instructions to produce a Primo prototype,  different from the product that they make and sell.

    We just finished the first edition of the Primo play-set open documentation, that includes the design files that we used to make our first prototype and a step-by-step guide to make your own version of the Primo play set. This “maker” version of our product can be assembled using rapid prototyping techniques and common tools like Arduino boards.

    We recently published a preview of this documentation just for our Kickstarter backers, who already started to build their projects and to translate the document in their language. The FabLab in São Paulo for example already translated it in Brasilian Portuguese, while other languages like Dutch, Italian and Japanese are now in progress.

    The whole documentation is completely transparent: it’s written in Markdown using Jekyll and GitHub pages. In this way it is very easy for creators to modify, translate and use it as a starting point for their projects.

    In parallel we are developing an industrial version of our product, using manufacture-quality materials and custom Arduino-compatible electronic boards.



    And if you want to read about the experience of a dad making a DIY version in 1 month and a half of work, follow this link.

    Primo is an Arduino At Heart partner. If you have a great project based on Arduino and want to join the program, read the details and then get in touch with us.

    The most advanced Lamp/Speaker is open source and also Arduino at heart

    cromatica digital habits

    Interacting with objects in a new way has always been the main focus of Digital Habits, a design studio based in Milan.  Today we are proud to announce they’ve become a partner  of the Arduino At Heart program with their new project called Cromatica (it was exhibited at the coveted Fuorisalone Milan Design Week in the Superstudio Temporary Museum for New Design and started the crowdfunding campaign just some days ago!).

    Cromatica is half speaker and half desk lamp: it can be controlled through a natural gestural interface, touch sensors or remotely via the Cromatica Android and iOS app. Designed to deliver both light and sound functions, Cromatica features wireless 4.0 Bluetooth connection for streaming music and a RGB lamp for multiple ambient effects.

    Cromatica is embedded with an Arduino allowing for a highly digital, multi-sensory music and desktop working experience.  It blends  light and sound functionalities in unexpected ways, taking IoT products to a new level of quality.  For example you can download the app for natural awakening: light will rise and music streaming will start allowing you to wake up to your favourite playlist, perfect for early mornings.

    Take a look at the video for the Natural Interaction:

    In the video below you can see how you can create your favorite ambient  to match with your mood:

    Innocenzo Rifino, Director of Digital Habits, told us:

    “The Cromatica is a multi-purpose light-speaker but it is also our vision of the evolution of electronics, a vision that is moving in a more human and open direction. Crowdrooster have helped tremendously by opening our product up to a wider community whilst giving us the chance to generate enough funding to share our concepts more widely.”

    The Cromatica is also true to its maker roots being Open Source and hackable, opening the doors for endless innovation from the maker community as it can be adapted to integrate with other tech and the Internet of Things. To enable this there will be a special ‘Maker Edition’ campaign reward complete with digital file to 3D print the shell.

    Take a look at their campaign Crowdrooster and make your pledge!
    Crowdrooster, the new ‘all tech’ crowdfunding site, introduced Cromatica as the first maker project available for funding on the site.

    Thanks for making our birthday so great! #ArduinoD14


    It’s been a couple of weeks since we celebrated with all of you the beginning of our tenth year. We’ve been receiving videos and pictures and want to share them in this post (Explore the tagboard of #ArduinoD14).

    The first Arduino Day around the World was a huge success largely due to the dedication of each of the communities joining the party! We had more than 240 community events sharing with us this moment of celebration and we sincerely appreciate the efforts and thank you again for the support within the Arduino Open Source Community!

    Once more we realised the importance of community by saying “Arduino is you.” Hardware, software, tutorials, and logistics aside, people enjoying time with Arduino are exemplary of the folks who make it fulfilling for us to continue with this adventure. Thank you!

    Here’s some awesome visual reports we received:

      • Antonius was at ITP in New York together with Massimo Banzi and Tom Igoe and made this video:
      • David Cuartielles featured in this video from Arduino Day Zaragoza:
      • Richard from Wevolver in Amsterdam organised a Show and Tell in collaboration with Ifabrica:

    Using RFID for a DIY Keepsake Box

    rfid keepsake box

    Mike Buss used an Arduino Duemilanove, Parallax RFID reader, micro servo, and piezo electric speaker to make a personalized, lockable keepsake box for his girlfriend’s birthday:

    The outside of the box is really simple: it just contains a button and an RGB LED. When she presses the button, the LED lights up green or red depending on if the box is locked. When she waves one of the three personalized RFID cards over the box, a little tune plays and the box unlocks.

    As part of the project I also did some cool trick with a Pololu pushbutton power switch to make the battery last a lot longer. Since the Arduino is only powered for a few seconds when listening for RFID tags, the battery lasts a lot longer. When the box is finished locking or unlocking (or after a small time delay), it sends a signal to the power switch to turn off the power and conserve battery life. The box has been running on the same 9V battery I put in 4 years ago!

    See what your Arduino is thinking with MicroView


    As some of you have already noticed on our social channels, we are thrilled to announce a new partner in the Arduino at Heart Program: MicroView, the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using an OLED display.

    Microview, by Geek Ammo, is versatile as it meets the needs of beginners and experts alike.

    For beginners the MicroView is the first Arduino to ship with built in tutorials. Beyond the tutorials, the MicroView’s OLED display helps to visualize what the microcontroller is doing. You can print print debug messages straight to the OLED display without needing to connect to the Arduino IDE. The immediacy of being able to see live sensor values makes the whole experience so much easier.


    A rich library saves experts time by allowing them to quickly display Strings, Counters, Gauges, Sliders, and Bitmaps with only a couple of lines of Arduino code.

    Marcus Schappi, Geek Ammo CEO, told us:

    “We’re proud that MicroView has been accepted to be part of the Arduino at Heart Program. By basing the MicroView on the architecture of the Arduino Uno, we’re standing on the shoulders of giants. We can’t wait to see what people make with the MicroView.”

    Arduino At Heart

    Their Kickstarter campaign is really going well, but the campaign only has a few days left, so get in quick and back the MicroView now so you don’t miss out!

    Teach kids how colors are made with the color machine

    color machine

    The Color Machine (La macchina dei colori, in Italian language) is a tool to teach children about the use and the operation of RGB color coding, which is used in all digital devices (TVs, smartphones, computers, etc.). It was created with Arduino Mega by an italian duo composed by Fabio Ghidini and Stefano Guerrini:

    Using 3 knobs you can increase the percentages of red, green and blue separately, and the LED strip at the top of the machine lights up consistently with the color mix choosen.

    The Color Machine has 4 different operating modes: “let’s create colors”, “guess the color”, “the names of the colors” and “demo”. Under the guidance of a teacher, children can play and learn at the same time to recreate colors with additive synthesis. This device is currently used in the educational workshops of Musil – Museum of Industry and Labour of Rodengo Saiano (Italy).


    This is the first propotype:

    How to monitor a domestic photovoltaic plant with Arduino



    ArdaSol is the name of a project for a solar energy monitoring system based on Arduino Mega and UNO, made by Heinz Pieren. It’s a system built to monitor energy production and consumption of a domestic photovoltaic plant:

    The ArdaSol Energy Monitoring System has 3 devices:

    - ArdaSol Display based on a Arduino Mega Board
    The master of the system, it collects the data from the two other ArdaSol devices, shows the data on the display, stores it on a SD card and sends it to a server in the internet.

    - ArdaSol Energy Monitor based on a Arduino Uno
    Measures the consumption of the energy, shows energy values on local display and delivers it on request to the ArdaSol Display.

    - ArdaSol Remote PVI Interface based on a Arduino Uno
    The photovoltaic inverter (PVI) has a RS485 interface, this is connected to ArdaSol Remote, which interacts as a gateway to ArdaSol Display. It converts the requests, coming with a radio signal to the PVI and vice versa.

    Arduino Uno Controlling a Lego Mindstorms Elevator

    Lego and Arduino

    NooTrix submitted us a 4-part tutorial to build a Lego Mindstorm Elevator controlled by an Arduino Uno:

     The elevator is built using components from an old Lego Mindstorms RCX 1.5. For the control part, we use an Arduino Uno board instead of the obsolete Lego RCX brick. The motor and sensors are from Lego. The connection to motor is done using a set of transistors organized in a H-Bridge.

    The goal of the project is to show how to control Lego parts (motor, sensors, …) using an Arduino:

    the elevator carries a smartphone and keep it level which is useful for taking snapshots of documents instead of scanning them. Full description, a step by step tutorial, as well as pictures, videos are available online.

    All circuit schematics and source code are released under a free open source license (creative commons).

    Growing your veggies with a smart greenhouse called MEG

    MEG presented at PopupMakers

    MEG is the world’s first social and automated greenhouse, part machine and part community, now on Kickstarter. Carlo D’Alesio and Piero Santoro, the designer duo based in Milan presented the prototype  at Maker Faire Rome and also at a PopupMakers event last year.

    MEG means Micro Experimental Growing system, runs on an Arduino MEGA 2560 which controls an automated “light engine,” water and nutrient tank, fans and sensors monitoring humidity, temperature, and pH. It’s smart because if you are not really good with growing plants, you can crowdsource parameters from other gardeners: your neighbour’s tomatoes won’t be more red than yours!


    Last saturday they celebrated Arduino Day in Milan and launched the campaign right there with us, where I took a couple of pictures of the prototype!
