Dave over @ PopSci shows you how to build an ambient LED project using an Arduino…
Ambient technology is the current rage for presenting information in a unobtrusive and, sometimes, sublime manner. Information suited for an ambient format ranges from complex number-laden data streams to simple one- or two-digit numbers. The idea here is that you can glean the same information by simply looking at the color of a cube, rather than consulting a sensor’s text output.
While this project doesn’t directly take advantage of ambient technology, it does show you a great method for generating a simple color-changing LED that can be integrated into any number of projects. By combining the open-source Arduino microcontroller circuit board with a “smart†LED called BlinkM, you can build a simple mood cube that randomly generates a spectrum of sumptuous colors.
By pairing a sensor with this Arduino-based mood cube to input data, you can create a more ambient-like experience.
