Using Arduino Esplora with graphical programming languages

via Arduino Blog

esplorascratch

Alan Yorinks shared on Arduino Community on Gplus a physical computing environment he created to make it easier for 10 and 11 year old’s to start playing. He picked up an Arduino Esplora, and wrote some software so that it could be controlled from the Scratch and Snap! graphical programming languages. According to Alan, the Arduino Esplora has on-board integrated sensors, actuators and make it a perfect match for the graphical programming languages that the kids love to use.

By combining an Arduino Esplora microcontroller with the esp4s library and either the Scratch or Snap! programming languages, that first line of code can be written in minutes!

Take a look at his documentation on Github.

A new version of the Arduino IDE (1.6.2) is available at the download page!

The Arduino IDE 1.6.2 features new one click install of boards and libraries.

With 1.6.2, two new menu items are available: “Sketch > Include Library > Manage Libraries…” and “Tools > Board > Boards Manager…”

We have written two guides that explain how to use them. Discover how to use the Library Manager and how to install support for additional boards.

If you don’t find your preferred library in the list, let us know: open an issue on github and request us to add the library you love!

Having such tools allow us to better and easier deliver updates for both cores and libraries: just open Library Manager or Boards Manager to find an Update button on the updatable items.

IDE 1.6.2 also includes a handful of bug fixes and improvements, also thanks to our fantastic community of hackers and makers:

  • Ever suffered of a super slow Tools menu? Solved! Ports list gets refreshed in background, so you won’t need to wait any more.
  • We have dropped support for Mac OS X 10.6 or older: previous versions of the IDE will remain available for download at the previous releases page.
  • A new EEPROM library, thanks to @Chris–A
  • Pre and post build hooks, thanks to @Wackerbarth
  • Various bug fixes, thanks to @Timmmm, @vicatcu, @arve0 and @Xuth

As usual, the complete list of fixes and credits is available here.

Don’t forget to report any issue you find, either on Github or on the Arduino forum: your help is very much appreciated. It doesn’t matter if you are not a tech specialist: every feedback adds value.

Session of work on 1.6.3 will start on Monday: we are now enjoying  Arduino Day!

An open hardware quartz crystal microbalance for ultra high mass sensitivity

via Arduino Blog

openQCM

Marco Mauro is a physicist currently employed as Scientific Coordinator at Novaetech, the first Spin-off Company of the National Institute for Astrophysics (INAF) in Italy. He shared with us all the info about a project he’s been working on  and based on Arduino Micro.

OpenQCM is a fully open source scientific microbalance capable of weighing mass deposition down to 1 billionth of gram:

The sensing core of the microbalance is a piezoelectric quartz crystal oscillator. The deposition of a very tiny mass on the surface causes the variation in the quartz frequency. openQCM belongs to a new generation of innovative smart sensor which boast high resolution and ultra high mass sensitivity. The open source strategy made the creation of openQCM available at low cost which represents a bit fraction of the cost of similar scientific products.

openQCM was built keeping in mind the emergent principles of the open source hardware movement. The open source hardware gives people the freedom to control their technology through the open exchange of all the project features, 3D design, electronics and software. The open hardware potentiality is even greater when it comes to hardware for scientific applications.

openQCM is exactly something like that, the first open hardware quartz crystal microbalance with applications in a wide range of scientific fields, such as chemical and biological sensing, material science.

openQCM has an Arduino Micro board inside at heart. By hacking the timer counter of the AtMega32U4 Arduino microcontroller, it is possible to measure the quartz crystal frequency variations using the 16 Mhz microprocessor clock. openQCM team has designed an Arduino Micro shield with an embedded quartz crystal oscillator driver circuit and a temperature sensor. The output of the quartz crystal oscillator driver is fed to the Arduino Micro timer counter and the analog value of the temperature sensor is fed to the analog pin of the board. This configuration allow you measure the quartz crystal frequency with a resolution of 1 Hz, which roughly corresponds to a mass resolution of 700 pg over the entire quartz surface in air.

One of the major challenge of an open hardware project is that such devices require funding to prototype and manufacture. That’s why the openQCM team have selected the 3d printing technology to keep high quality and low cost. Using 3d printing to print out the prototypes via the SLS process from OS Formiga P100, P110, P395, and P730, the openQCM team created the device’s parts, which required a precision down to 60 µm.

The open source concept made openQCM publicly available so that anyone (scientists, technology enthusiast, makers, hobbyist …) can study, modify, and develop the hardware based on the original design. openQCM is now working and ready to win the heart of the scientific community and more.

Go and make one yourself!

Dear Arduino community, we need to talk

via Arduino Blog

This is the message Massimo Banzi’s just published on the forum.

——————

Today is the day of a solar eclipse, some of these are once in a lifetime events.

Arduino is definitely one of the events that will define my life along with many other people’s life.

I’m feeling incredibly blessed to have contributed to create this amazing community which gathered around the idea that we can empower people to master complex technologies and unleash their ability to create with them.

Dear community I’m sorry I didn’t comment earlier, I was keeping quiet to try to find a resolution to our internal issues that would not damage you, the community.

We’ve been so committed to keep the issues internal that for a year we haven’t receiving any royalty from the boards made in Italy, but we continued to work hoping to find a solution. I’ve told the story to Make read it if you want to know more.

Now the other party has abandoned the negotiating table and, after a lot of recent events, the cat is out of the bag. I owe you to be part of what is going on.

We created Arduino based on a set of values that have enabled the community to grow, touch any kind of people and contribute to changing the world a bit.

I am here to say that we will continue to fight so that Arduino stays true to those values. There is only one Arduino and there is only one Arduino community. We’re strong, we’re having a positive impact on so many people’s life.

We have so many news we want to share with you but be patient until Arduino Day, let’s celebrate together the amazing community we are (261 Global events!!!) , and you’ll know more.

I’m sure you have a lot of questions an we’re going to try to answer them in due time, compatibly with the fact that lawyers are involved and I can’t say too much.

An eclipse is just a temporary moment of darkness, but soon after the sun comes back shining.

The sun is about to come out, wear your sunglasses!!

What if kids could hack a ball? (Prototyped with Arduino!)

via Arduino Blog

hackball

Hackaball is a smart and responsive ball that children can program to invent and play games. It was recently backed by more than 1000 people and reached the goal!

As many other projects on Kickstarter, Hackaball was initially prototyped with Arduino using sensors that detect motions like being dropped, bounced, kicked, shaken or being perfectly still.

hackball2
We got in touch with its team and asked them to tell us a bit more about the creation process:

Our early versions of the ball worked with the Arduino Uno board, progressing to a breadboard Arduino and then making our own SMD designs with the Uno. In the latests prototypes we used the Arduino Leonardo and our current version runs on the Arduino Mega. Our production version will run on an ARM chip.

We hope to offer Arduino Compatibility as one of our stretch goals in the Kickstarter, so that people can buy a board and put their own code on it using the Arduino software, effectively moving one step up from the app in terms of hacking the ball and making it do what you want it to do. We also believe many adults would love an interactive ball that they can control and design their own interactions – its packed full of features! Hopefully it will also allow kids who’ve outgrown our app to experiment with our technology in a more challenging way, bringing longevity to the product.

We’ve approached the kids who’ll play with Hackaball as the future Makers. The idea of hacking and getting close to technology starts with how the ball first arrives in your home. Kids open the packaging to find the ball is broken: Hackaball has crash-landed on earth and needs to be put back together again. After their first achievement, making the ball, kids are challenged to play games, change existing ones, fix broken games and create new ones from scratch.

We specifically designed the ball and packaging to be gender neutral – making it feel accessible to both boys and girls from the very beginning. We also expanded on the ability of the ball to include both hard and soft skills – from the tactile and linear computational thinking, to the storytelling and imagination-driven game creation, teaching a new generation of Makers to combine technology and creativity. We think that the kids who play with Hackaball would move on to Arduino in their teens!

 

You still have some days to back the project and help them reach the stretch goals, making Hackaball even more hackable!

Getting Started with Intel Edison Mini Breakout Board

via Arduino Blog

Tutorial_intel2

Let’s start exploring a bit more about Intel Edison. As you may already know, Intel provides 2 different hardware platforms to work with Edison development board: the core module is called Intel Edison Compute Module, while the 2 extension boards are called Intel Edison Arduino Board and Intel Edison Breakout Board respectively. We refer to them as the Arduino module and mini-breakout board, respectively. The tutorial of this week is called Getting Started with Intel Edison Mini Breakout Board:

It is probably more common to use the Arduino module, since it’s easy to use and has many useful features, most notably the pin headers. However, the mini-breakout’s main advantage comes from its size and possible use as a wearable.

In this tutorial, you’ll get more familiar the mini-breakout board, learn how to use it for basic tasks, and then build a small “blink” example based on this knowledge.

Build Arduino-based IoT apps with Temboo Conditions features

via Arduino Blog

conditions-temboo

Last week Temboo just added new Conditions features to its IoT Mode interface, making it even easier to connect your Arduino to the Internet of Things! Now, the functionality of Temboo’s Device Coder has been extended to all 2000+ Choreos in the Temboo Library, meaning that data collected from sensors attached to an Arduino Yún can be used to trigger any cloud process, and responses from the cloud can be used to trigger all sorts of hardware actions on your board.

Using IoT Mode on the Temboo website, you can automatically generate ready-to-run Arduino code to execute Choreos from your board without having to write a single line of code yourself—just specify which board and shield you’re using and what Choreo you’d like to run, and all the necessary code will be generated immediately in your browser. And you can also now visually specify what sort of hardware inputs and outputs you would like to use: the code to connect them to your Choreo will be generated as well.

The visual interface includes a pin selector tool that lets you choose which pins you want to activate and how you want them to interact with the Choreo you are running. The pin selector identifies the pins on your board that are available, and also indicates whether those pins are configured to work with digital or analog I/O. Like the generated code itself, the pin selector interface will change to reflect the board and shield you’ve chosen to work with.

temboo-conditions-screenshot-arduino

Conditions make it quick and easy to build a massive range of IoT applications, like a thermometer that sends SMS alerts, or a motor that runs when it receives an email. Just specify how you want your pins to interact with the web services you are using, and thanks to Conditions, what you specify will be reflected in a complete, production-ready program generated instantly in your browser. Try it out, and email hey@temboo.com to let them know what you think!

Every word is like an unnecessary stain on silence

via Arduino Blog

silence

« Every word is like an unnecessary stain on silence and nothingness » is a sentence from Samuel Beckett but also the title of Eugenio Ampudia’s last artwork created and installed with the support of Ultra-lab  and running on Arduino Mega and GSM Shield:

The exhibition room has in its center a rectangular mirror made of water that reflects the room and the visitors. The perfect still water, metaphor of silence, is broken by the irruption of sporadic waves. These movements, the stain on silence, are provoked by the visitors’ interactions. In the heart of the water tank, a dispositive is able to receive calls and to open a valve. To each visitor’s call, so a series of movements is generated and break the calm.

Ultra-lab realized the technical part of the artwork thanks to an Arduino Mega, the Arduino GSM shield and various valves open and close by the Arduino Mega when a call is received by the shield. The dispositive is particularly interesting for its adaptation in a water context and for connecting valves.

Thanks to it, the artwork succeed to express beautifully the paradox between a destructive attraction for words and communication to which it’s hard to resist in order to prefer a finally inaccessible contemplation.

The work can be visited in the exhibition room Abierto X Obras in in the Spanish art center Matadero Madrid until the 17th of May 2015 and below you can watch a video interview with the artist:

Encrypting messages with Cuckoo and Arduino Yún

via Arduino Blog

cuckoo

Jochen Maria Weber is a Researcher and Designer at the intersection of Interaction- and Industrial Design. He shared with us Project Cuckoo, a project running on Arduino Yún and looking at our interactions with intercepted social networks and how alternative ways of communicating might change them:

Twitter, Facebook, Google+ and co. collect our data and are forced to have a backdoor for state surveillance. Therefore Cuckoo encrypts messages into randomly generated words, meanings and noise in order to scatter them over multiple communication networks simultaneously. Each letter of an original message gets translated into complex forms of certain length forming new sentences. Those sentences get posted to aforementioned social networks, next to randomly generated noise-sentences for distraction. The encryption method can be changed with every new message. Any receiving Cuckoo-unit following the respective social network accounts can filter and decrypt the important posts according to their encryption method and time stamp. Cuckoo combines social networks to build a hidden one on top of their infrastructure. An egg in the others’ nests.

Cuckoo uses an Arduino YUN to connect wirelessly as a stand-alone device to the internet. It also does the en- and decryption of all messenges and made it comfortable to connect to Twitter, Skype and Tumblr API with Temboo.

Take a look at the video on Cuckoo’s website.

Play your emotional state with Social Vibes and twitter

via Arduino Blog

mabos2-2

Social Vibes’ is a Masters Degree (MSc.) project, in Interactive Media by Cian McLysaght, at the University of Limerick, Ireland. They shared with us their project, running on Arduino Uno, composed by a physical artifact designed and created specifically for an installation adopting the fundamental sound mechanisms used in a vibraphone, know also as a ‘Vibe’:

The instrument consists of twelve musical tones of different pitches. The music created on the instrument is derived from a continuous stream of input via multiple users on Twitter and the explicit interaction from Twitter users, tweeting the instrument directly to the project’s, “@vibe_experiment” Twitter account. Data associated with the emotional status of Twitter users, is mined from the Twitter network via Twitter’s open source, application programming interface (API).

For example if a user tweets “The sun is out, I’m happy”, the code I’ve written will strip out key words and strings associated with the user’s emotional state, within the tweets, ie “I’m happy”, and translate this to a musical notation. Mining Twitter’s API, allows a continuous stream of data. These emotional states are then mapped to specific notes on the physical musical instrument, located in a public space. The tempo of the musical expression will be entirely based upon the speed and volume of the incoming tweets on the Twitter API.

Twitter users who are both followers and non followers of the musical instrument’s Twitter account (@vibe_experiment) can tweet directly to the instrument and this direct interaction will be given precedence, allowing user’s who tweet directly to have their emotional state ‘played’. This allows users to hijack or take over the instrument and experiment with it in a playful manner, but also allows those with musical knowledge the potential to compose simple musical arrangements. When users are not tweeting the instrument directly, then the instrument will revert to mining the Twitter API.

To entice users to interact and observe the action of the instrument there is a live streaming broadcast of the instrument via Twitcam on the Vibe’s Twitter account. This is a live streaming broadcast of the instrument via Twitcam on the @vibe_experiment account. Twitcam, is Twitter’s built in live-streaming platform. This simply requires a webcam and a valid Twitter account.

The instrument constantly tweets back updates to it’s own Twitter account to not only inform people of the general status but also to engage users to interact directly with the ‘Vibe’.
