Voyage Boats
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.

How Breakout Works
Breakout is a tool for prototyping browser based interfaces for physical control. It uses Arduino for the physical part and HTML/Javascript for the interface.

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.
