Digistump has recently announced a partnership with Particle over cloud infrastructure that may well be a signal that the diasporan expansion in microcontroller market may be coming to an end.

Blynk is a new platform that allows you to build interfaces for controlling and monitoring your projects from your iOS and Android device.

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 hey@temboo.com to let them know what you think!
A few years ago, the most common method to put an Arduino project on the web was to add a small router loaded up with OpenWrt, wire up a serial connection, and use this router as a bridge to the Internet. This odd arrangement was possibly because the existing Arduino Ethernet and WiFi shields were too expensive or not capable enough, but either way the Arduino crew took notice and released the Arduino Yun: an Arduino with an SoC running Linux with an Ethernet port. It’s pretty much the same thing as an Arduino wired up to a router, with the added bonus of having tons of libraries available.
Since the Yun is basically a SoC grafted onto an Arduino, we’re surprised we haven’t seen something like this before. It’s an Arduino shield that adds a Linux SoC, WiFi, Ethernet, and USB Host to any Arduino board from the Uno, to the Duemilanove and Mega. It is basically identical to the Arduino Yun, and like the Yun it’s completely open for anyone to remix, share, and reuse.
The Yun shield found on the Dragino website features a small SoC running OpenWrt, separated from the rest of the Arduino board with a serial connection. The Linux side of the stack features a 400MHz AR9331 (the same processor as the Yun), 16 MB of Flash, and 64 MB of RAM for running a built-in web server and sending all the sensor data an Arduino can gather up to the cloud (Yun, by the way, means cloud).
All the hardware files are available on the Yun shield repo, with the Dragino HE module being the most difficult part to source.
This lamp which [Bablondeemu] built will add a little whimsy to your home decor. The project started as coursework for a Digital Art and Installations class. But the remote controlled color changing cloud ended up being a pretty neat gift for his little brother.
The prototype uses an Arduino, breadboard, and a collection of LEDs to perform its tasks. [Bablondeemu] admits the next revision should have a standalone circuit board. The electronics are housed in a clear plastic container which was then adorned with Polyfill stuffing which would commonly be found inside a decorative pillow. The polyester fibers do a great job or filtering and diffusing the light. But they don’t seem to interfere with the incoming IR signals from the remote control.
If you like the idea of creatively shaped diffusers you should take a look at this giant LED lamp. It’s molded to look like a through-hole package with the leads hiding the power cord.
codebender is web-based IDE, mainly built with HTML5 and Javascript, that focuses on the development for the Arduino platform. Since it is going to be used directly from the browser (note that currently codebender is still beta), it will further simplify the whole development process, avoiding the installation of software and libraries on the local machine.
From the home page of the project:
We want to lower the barrier to entry, which is necessary to help everyday people start their first project, become makers and advance technology instead of using it. codebender requires no installation, so you can get started with Arduino programming the minute you get one in your hands! And with the development tools we provide, you can do so faster and easier! codebender also stores your code on the cloud, so it’s safe and accessible from anywhere, anytime.
Several nice features will be available soon, such as remote flashing: together with an Ethernet shield flashed with a properly designed TFTP bootloader, you will be able to upload a sketch remotely, over the internet! Another nice feature regards its integration with the open documentation available on the Arduino website, which will be accessible directly from the IDE by selecting a piece of code and, then, by pressing ctrl+space.

In his blog, Charalampos describes his experience with SeeedStudio’s Grove Ear-clip Heart Rate sensor and Cosm (former Pachube) cloud service. The employed sensor is quite cheap and can detect heart pulses from the ear lobe, by measuring the infra-red light reflected by the tissue and by checking for intensity variations.
By connecting this sensor with an ADK board and, in turn, with an Android smartphone, Charalampos implemented a portable heart-rate tracker, which is used to send the recorded data to Cosm cloud service.
