Its currently on sale in the Arduino store. At 69€, it’s not cheap, but it will be good for projects that need Internet access where wifi isn’t available.
300 little “paper boats” are afloat at Canary Wharf. The Voyage installation, on display through February, was created by Aether-Hemera. Each boat is lit by a multi-colored LED, which visitors can interact via their mobile phone.
To make all of this work, a Raspberry Pi, an Arduino and some custom circuitry are used. Aether-Hemera has a nice, behind-the-scenes look at how this installation was created.
With Breakout, accessing all of the digital and analog pins on the Arduino is quite straightforward. One can create a web interface for both input and output. A number of examples are provided, such as using buttons to turn a LED on and off, displaying the state of a physical pushbutton and graphing the value of an analog input.
If you’re curious, and have an Arduino nearby, try out the getting started examples, you’ll have a web controlled circuit running in just a few minutes.
