Selfie Plant is an interactive installation taking pictures of itself using Arduino Yún, Facebook Graph APIs and then uploads them to Facebook. It was developed by a group of students at the Copenhagen Institute of Interaction Design during “The secret life of objects” course held also by Arduino.cc team. The final prototype was placed in the exhibition of the school, to see the interaction of the audience with it and you can see the result on Facebook.
The Selfie Plant is an attempt to provoke some thoughts above genre of expression. The Selfie Plant expresses itself in the form of nice-looking selfies, which it clicks according to its mood, weather or occasion. It mimics human behaviour, by giving it’s best pose and adjusting the camera angle to take the perfect selfie.
In the documentation on Github you can find all the details of the project composed by an Arduino Yún, controlling 2 servo motors and adjusting the positions of the plant and the camera stick; a python script (facebook.py) which communicates with Facebook’s graph API to post the captured photos on plant’s Facebook profile. In addition you’ll need also a LED Matrix, a Bread Board and 5 Volt Battery.
Here’s a preview of the diagram:
Comelicottero is a quadcopter based on Arduino Yún created during the Master in Computer Science at the Universita’ degli Studi of Milan (Italy) by Simone Castellani, Giovanni Intorre and Andrea Toscano:
The idea was to build a drone able to be controlled through WiFi from any PC, tablet or smartphone . Comelicottero is equipped with an accelerometer and a gyroscope for the stability obtained by a PID-based control system. Since Servo library is too slow for the quadcopter dynamics, an hardware PWM was implemented to obtain a 400Hz PWM signal.
The communication between the ground station on a PC and the quadcopter relies on WiFi and, in order to get better results, Bridge library was replaced with an efficient python script on OpenWRT-Yun. On top of that all the code was written to maximise Arduino Yún capabilities. The Navigation System has been designed, simulated on PC, implemented and tested. The autonomous navigation is going through an additional testing due to magnetometer interferences with motors’ magnetic field.
The user can control and monitor data coming from the drone using a gamepad attached to a laptop with a custom software installed.
The sketch and all the documentation will be soon available on GitHub and released with GNU license. In the meanwhile follow their Youtube Channel for updates.
The apparent lull on the Arduino front the last few weeks was just the calm before the storm that is the Bay Area Maker Faire (BAMF). Both companies claiming the Arduino name were there over the weekend, with news and new products in tow. Ironically, you could see from one booth straight over to the other. Small world.
Perhaps the biggest news from Arduino LLC is that hacker-friendly Adafruit is now going to be making officially-licensed boards in the US. Competing with this news, Arduino SRL brought its new boards, including the Yun Mini and ARM-powered Arduino M0. And [Massimo Banzi] and Arduino LLC seem to be taking an end-run around the Arduino SRL trademark by announcing the “Genuino” brand for European production. For all the details, read on!
As announced by [Massimo] in his “State of the Arduino” keynote speech at the BAMF, Arduino is licensing Adafruit to produce a range of the “most-requested” Arduino boards at their factory in New York. So those of you looking to support Arduino LLC with your purchases also get to help line [Ladyada]’s pockets at the same time. That’s a big win in our book.
It’s not a complete surprise that Adafruit should get tapped as a US fab for Arduino.cc. They’ve been selling the boards and producing copious Arduino-related tutorials since their beginnings in 2005. More recently, Adafruit partnered with Arduino LLC to create the Gemma board, which is basically an ATTiny85-based Arduino-a-like in a tiny round, wearable-friendly board. (If you’re familiar with the Adafruit lineup, it’s essentially a Trinket in the round format of a LilyPad Arduino.)
Indeed, after the deal is done and the dust has settled, it’s a bit surprising to us that this hasn’t happened earlier, what with both Adafruit and Sparkfun producing licensed boards and Arduino LLC looking for new manufacturers. Anyway, good job Adafruit and Arduino (LLC)!
Arduino SRL had its Yun Mini, which is essentially a smaller version of the Yun — a mashup of an Arduino Leonardo with an OpenWRT-capable router chipset. We’ve reported on these previously but it’s fun to see them in the flesh.
The M0 is interesting. Before the troubles began, Arduino designed an ARM-M0+ based board with Atmel. Now Arduino LLC has it listed on their website as the Arduino Zero, but still hasn’t got any for sale yet. Arduino SRL has the boards on their website as the Arduino Zero Pro, with a different name, but is now touting this version as the “M0 Pro”. What’s in a name? Not much. The circuit layouts and parts appear identical.
Both of the Arduino companies are working on getting your Arduino development into “the cloud”. (Conscience compels us to note that “the cloud” is actually just other people’s computers.) Anyway, this essentially means new web-based and browser-based versions of the IDE that tie into web services. Interestingly enough, the two companies have different takes on what that entails.
Meanwhile, Arduino LLC displayed previously announced their alternative development platform, Arduino Create. Arduino Create lets you write, compile and upload sketches “directly from the browser with the Arduino Web Editor”, and store your code in the “Arduino Cloud”. Arduino Create looks slick: certainly a lot better than the homely Java IDE that we’re all used to. It’s too early to tell what this “cloud” is all about, but it looks like it will include code sharing, schematic and wiring hookup storage, and easy sharing among users.
We already use blogs, Hackaday.io (shameless plug!), Github, and other “cloud” services to store our projects and code, so we’re not entirely sure what either of these portal offerings will bring to the table. It’s 2015, is anyone still hurting for project hosting space on the web?
Cynically, we note that both of these companies are in a battle to “own” the Arduino community and that getting people to host code and projects on their servers is an obvious strategy, and providing a web-based IDE to facilitate this capture is the tactic.
Finally, as if it weren’t bad enough with Arduino LLC and Arduino SRL, [Massimo Banzi] also announced that licensed boards for the European market will be sold under the new “Genuino”.
Actually, this is a pretty cagey maneuver, because it side-steps the European trademark issues (which [Massimo] referred to as “the bullsh*t” in his talk) and is a cute name to boot. “Genuine”, get it?
Our take? As [Massimo] almost said in this video interview with Make, “a rose by any name would smell as sweet.” If Arduino LLC loses the trademark lawsuit in Italy, they’ll not be allowed to sell boards using the “Arduino” name. The best way to limit the damage in the future is to make the switch now, while everyone is watching, and give the market time to adapt.
Our friends at Temboo just introduced a new way to log data from an Arduino Yún to the cloud. Called Streaming, it lets you visually select the sensors attached to your Arduino that you have gathering data, and then stream that data to the cloud IoT platform of your choice.
Streaming also makes it easy to switch where you’re sending your data once your application is running, without requiring any hardware or software updates. Right now, Streaming works with Microsoft’s Power BI and Google’s BigQuery, but Temboo will be continuing to add more platforms in the future. As with Temboo’s other Arduino programming tools, Streaming lets you generate all the code you need for your application right in your browser, and tailors that code to the parameters that you specify. It makes it much easier to store sensor data from your Arduino in the cloud, and to analyze the datasets that you build.
This video shows you how it works:
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.
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 email@example.com to let them know what you think!
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.
Maker Faire Rome video interviews – “What have you built with Arduino?” – A couple of new protagonists for our short series:
December is finally here and we can start thinking about indoor or outdoor decorations for the holiday. Christmas lights are an excellent way to light up any event and a user on instructables wanted to be able to control the lights remotely with text messages.
Check his 12-step tutorial and take a look at the bill of materials:
- An Arduino Yún – You could use another Arduino with a Wifi Shield though.
- A Protoshield with (or without) a tiny breadboard
- A regular breadboard will work as well, but will be less compact.
If you want to solder more, you can just use a small circuit board instead.
- A 5V relay
- A piezo buzzer
- A battery operated Christmas decoration (It’s not even Thanksgiving, so I’m using a Halloween decoration)
- A Temboo account
- A Twilio account
The connected birdhouse is a project prototyped during a workshop ran by Massimo Banzi at Boisbuchet, last August in France. It was developed using Arduino Yún, by Valentina Chinnici, who shared with us the project, and two other students taking part to the week of learning-by-doing around the theme of the Internet of Trees.
They redesigned a traditional object, a wooden birdhouse to be placed outdoor, and connected it to a lamp shaped like a nest, to be placed indoor:
The connected birdhouse was in fact an interactive object able to communicate to the nest/lamp the presence of a bird inside the house, and accordingly to a color coded signal was giving also some informations about the size of the bird itself. In the event of a bird entering into the house, the nest/lamp remotely controlled via WiFi by an Arduino Yún, was turned on. The nest/lamp received the notification from the birdhouse translating it firstly with a rainbow effect. After few seconds the light changed according to the weight of the bird (green, yellow or red).
The LED strip used for the nest lamp was an Adafruit Neopixel strip controlled by an Arduino Yún.
On this blog you can find the sketch to make it work and create one yourself.
