Last month we launched the first of a series of tutorials hosted on our Youtube Channel and created by Max of MaxTechTV in german language.

Today we are publishing the second video called “Pimp-up your camera with an Arduino timelapse“. The video explains how to connect an Arduino UNO with you camera and shoot pictures, for example, every 1, 5, 10 seconds to create wonderful videos of slow processes that would normally appear subtle to the human eye.

Enjoy the tutorial below and share with us the results of your experimentations!

In conjunction with the release of the new version of the Arduino IDE and the Arduino Robot, we’re also putting out a TCT LCD screen. The screen was developed in conjunction with Complubot and the library relies on the Adafruit GFX and ST7735 libraries.

The screen lets you do all sorts of fun things, like play games or lose the serial monitor to see the values from sensors.

The Arduino specific library, named TFT, extends the Adafruit libraries to support  more Processing-like methods. You can write text, draw shapes, and show bitmap images on the screen in a way that should be familiar to users of Processing.

The screen works well with all types of Arduinos with a little bit of wiring, and fits perfectly in the Esplora and Robot sockets. In addition to all this other goodness, there’s a SD card slot on the back for storing pictures and other data.

If you want to learn more about the screen and what it’s capable of, check out the TFT library page, getting started guide, and product page.

You can buy the TFT screen from the Arduino store now!

If you have something cool you’ve made with this, let us know!

Some weeks ago I read an article on the New York Times talking about Kickstarter. The author was exploring the logic of the platform and especially in which way backers shouldn’t really be considered like investors. They aren’t because their main aim is not looking for the project that will give them the greatest return on their money.

Kickstarter as a phenomenon is made much more comprehensible once you realize that it’s not following the logic of the free market; it’s following the logic of the gift […] People contribute to them because they’re friends who know the artist personally; they’re fans engaged in a highly personal if unidirectional relationship with the artist [creator]; or simply because they’re intrigued by the project and want some sense of participation in it.

Here we are then, highlighting  two Arduino-based projects because we are intrigued by them and hope you like them too.

The Mood Lamp project by Vittorio Cuculo, is a system using interactions to communicate an emotional state to a physical object and receive back  a coherent response. In particular, through your facial expression you communicate your emotional state to an RGB color lamp . The lamp, at this point, will respond to the interaction by changing the color of the light emitted in accordance with the emotional state inferred.

The aim of the systems is to remove the mediation between human and machine typical of classic interfaces. Among the modes of natural interaction we usually have gestures, gaze tracking and facial expressions. The latter are particularly relevant because they play a fundamental role in nonverbal communication between human beings.

Regarding the man-machine interaction, the ability to recognize and synthesize facial expressions allows the machine to gain more communication skills, on the one hand by interpreting the emotions on the face of a subject, and on the other by translating their communicative intent through an output, such as movement, sound response or color change.

An IKEA lamp becomes a Natural Interaction system which senses human emotional states through facial expression. It uses OpenCV for image processing and analysis to identify emotional state through the movements of face’s fiducial points. The lamp, made with an Arduino Duemilanove, changes its color to represent the user’s current emotion.
In particular, it receives via serial communication, the values of pleasure, arousal and dominance, following the PAD emotional state model, as inferred from the facial expression and changes accordingly the color of the RGB LEDs.

Massimo Banzi announced it some minutes ago during his annual “The state of Arduino” presentation at Maker Faire Bay Area:  Arduino Yún  is the first of a revolutionary family of wifi products combining Arduino with Linux.

Yún means “cloud” in chinese language,  as the purpose of this board to make it simple to connect to complex web services directly from Arduino.

Designed in collaboration with Dog Hunter, a company with extensive experience with Linux, the board adopts the Linino distribution which provides signed packages to ensure the authenticity of the software installed on the device.

Historically, interfacing Arduino with complex web services has been quite a challenge due to the limited memory available and they tend to use verbose text based formats like XML that require quite a lot or ram to parse. On the Arduino Yún we have created the Bridge library which delegates all network connections and processing of HTTP transactions to the Linux machine.

Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.

Like a Leonardo, it has 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator and a micro USB connector.

Like any modern computer, it’s Wi-Fi enabled, it has a Standard-A type USB connector to which you can connect your USB devices and it has a micro-SD card plug, for additional storage.

The Yún ATMega32u4 can be programmed as a standard Arduino board by plugging it to your computer with the micro USB connector. And you can also program it via Wi-Fi.

When the Yún is turned on for the first time, it becomes an Access Point, creating a Wi-Fi network named “Arduino”. Open your browser and go to the webpanel: configure the board by entering your Wi-Fi network name, type and password. Click the “Configure” button to restart the board and have it join your home network. Opening the IDE, you’ll see it listed in the “Port” sub menu with its IP address instead of the serial port name.

Using the Bridge library in your sketches, you can link the 32u4 to Linux, launching programs and scripts, passing them parameters (sensor readings for example) and reading their output, thus creating a strong integration between the creativity of your sketch and the power of Linux. The Yún supports Shell and Python scripts out-of-the-box but you can install a wide range of open source software and tools.

For the Linux geek in you, Yún can be reached with SSH:  that means you’ll be able to customize it in whatever way. And you’ll always be able to reset it to its factory settings.

On top of that to make it even simpler to create complex applications we’ve partnered with the innovative startup Temboo which provides normalized access to 100+ APIs from a single point of contact allowing developers to mix and match data coming from multiple platforms (for example Twitter, Facebook, Foursquare but even FedEx or PayPal).

Arduino Yún will be available at the end of June at the price of 69$ + taxes.

We’re happy to announce the release of a new version of the Arduino software, version 1.0.5. Barring any unexpected bugfixes, this is the final planned release of the 1.0 series of the IDE. Future releases will be from the 1.5 branch that has been in beta since last summer.

With that excitement out of the way, let’s get to the new features :

•  New library import functionality to install libraries directly from a .zip file in the IDE. You can see more information about this on the installing 3rd party libraries page.
• A Windows installer, which will hopefully streamline the process of setting up the IDE and drivers.
• Windows signed drivers. This means Windows 8 will no longer prevent you from installing Arduino drivers.
• The application is signed for OSX 10.8 (this was part of 1.0.4, but we thought it was so nice it deserved another mention).
• Updated WiFi library with UDP support.
• Support for the Arduino Robot and TFT screen. The TFT library is based on a number of Adafruit libraries, and the Robot library relies on many 3rd party libraries.
• Various bugfixes and optimizations, look at the release notes for a complete description.

Special thanks to everyone who contributed on this release. You rock.

Future releases of the IDE will support multiple architectures (like the ARM used in the Due). There is also a new library and 3rd party board implementation being introduced. You can read more about these on the 1.5 library specification and 3rd party hardware support pages

You can download Arduino 1.0.5 from the software page.

The world’s most diverse showcase of creativity and innovation in technology, craft and science is starting tomorrow in San Mateo, California and the Arduino team will be there with more than a couple of new things to present.

First of all, finally and officially the Arduino Robot will be alive and running around the Arduino tent to bring you into the world of robotics. Designed with Complubot, the 4-time world champions in Robocup Junior robotics soccer, the robot allows for endless hours of experimentation and play. It is a self-contained platform allowing you to build interactive machines to explore the world. As all the other Arduino products you can use it as it is, modify its software and even add your own hardware on top of it: it is perfect for the novice but also for those looking for their next challenge.

As you may have read in the article published on MAKE some days ago, The Arduino Robot is the result of the collective effort from an international team looking at how science can be made fun to learn and we loved to share its story. Connected with this aim, David Cuartellies – head of Arduino Verkstad, the Arduino office in Malmö (Sweden) – during Maker Faire Bay Area will present the Castilla Education Project  aiming at evaluating the use of Arduino and other open source tools in the schools of Spain. He’ll especially focus on the way content was created and validated in an experiment involving 24 schools, 30 teachers, over 500 kids, and a 6-members design team.

On the topic of education also Michael Shiloh — Coordinator of Education materials for Arduino, will be on the Education stage on Sunday  at 4.30pm for a Q&A on how to use Arduino boards and how to prepare material for teaching.

Then we’re happy to announce that Arduino is releasing the new version of the Arduino IDE and the new TFT screen. TCT LCD library relies on the Adafruit GFX and ST7735 libraries.   The Arduino specific library, named TFT, extends the Adafruit libraries to support more Processing-like methods. You can write text, draw shapes, and show bitmap images on the screen in a way that should be familiar to users of Processing.

If you want to hear all these news from the voice of Massimo Banzi, don’t miss the center stage of Maker Faire Bay Area, saturday 18th of May from 1.30 and come to visit us at the Arduino tent (see map below for directions).

Nel  weekend all’inizio di maggio  l’Arduino Tour ha fatto tappa a Napoli per una presentazione e un workshop di due giorni in cui i partecipanti hanno sperimentato principalmente su due fronti.

Nel primo, sfruttando della vernice conduttiva BareConductive, è stato creato un disegno su una tovaglia: uno pseudo logo di Riot, lo spazio che ospitava l’evento. Dopodichè questo circuito pitturato è stato collegato ad Arduino UNO, connesso a sua volta ad un pc su cui giravano il software di bridge Serial-Midi (già visto a Verona) e Ableton. In questo scenario, usando il disegno e il proprio corpo (e pure l’altrui!) come un unico circuito, è stato possibile generare una grande varietà di suoni.

A completare il tutto, un vecchio Stylophone hackerato a fare da sottofondo! Qui qualcuno si è dedicato alla progettazione e realizzazione della pittura, altri all’interfacciamento Arduino-Midi, altri alla musica, altri allo Stylophone.

Il secondo fronte era dedicato al monitoraggio di consumi e all’Internet delle Cose. E’ stata realizzata una postazione per il monitoraggio di consumi, temperatura e luminosità e invio degli stessi a Emoncms (progetto OpenEnergyMonitor). In questo gruppo l’intenzione era di realizzare sensori di consumo a partire da materiale di recupero, anche se poi si è utilizzata una pinza amperometrica. Un altro gruppo ha invece utilizzato una nota centralina di monitoraggio wireless di consumi (CC-128), che debitamente hackerata è stata interfacciata ad Arduino. Anche in questo caso i dati recuperati venivano inviati a Emoncms Qui qualcuno si è dedicato al CC-128, altri alla configurazione standard, altri alla dashboard su Emoncms.

Qui sotto potete vedere alcune foto dal nostro profilo di Flickr e nel caso vi venga voglia di partecipare al prossimo workshop, prenotatevi per la tappa di Alessandria il prossimo 1 e 2 giugno!
