That's Smart.

The Project:
Smart Systems describe and analyze a situation, makes decisions and takes action on the available data, hence performing smart actions. Smart Systems address environmental, societal and economic challenges like limited resources, climate change, aging population, and globalization.

The project is to network our four Arduinos over the internet, sending and receiving data from feeds via Pachube to create some sort of Smart System.


Initial Ideas:
Initial discussion and brainstorm of ideas, we were exploring the concept of cooperative decision making. We got initially quite excited during a simple exercise where two people were each controlling an analogue input (potentiometers) to collaborative determine the position of a single ellipse on screen.


We like the idea of having something physical and tangible resulting from the collaboration, not just something that exists while it is operation. We discussed creating a creature powered by an Arduino which took input from the other Arduinos - perhaps by various sensors - to determine its physical movement and position on a canvas and create a sort of art work.


We like the link between the various representations of data which would come as a result: the physical input - pressure, light, movement - to the binary data read and understood by the computer and program, to the data it outputs in a form we can understand - i.e. analog value from 0 to 1023 - and finally the physical output of a painting which documented all the others in an abstract manner.


We put a lot of thought into what the more of the conceptual meanings and implications of each aspect were but we found it was all too open and hinged mostly on this idea of a physical result.


Personally, I thought we could adapt it to the input coming from pressure sensors placed around town (stationary) or even attached to the bottom of our feet (mobile) and rather than a flat output, having the creature with a bulldozer sort of attachment and pushing around sand.

This way, it would still create some sort of physical result which would be different every time it was run. The link between the input and the output, though initially a bit obvious, was the effect of the human footprint or existence on earth. Perhaps even some twist on a pedometer.

The Idea:

After further discussions, we changed our idea considerably which started with the idea that because we would be communicating our Arduinos over the internet from our own houses, we should control something in each others houses.

So we took the simple idea of a light switch.
We are planning on building a fixture which you would attach to on top of your light switch. You cannot actually access the light switch but instead, there is another switch on top of it. The actual switch (the one on the wall of the house) is activated by a servo physically changing it.


However, only three people out four can have light at any given time. The system will make the decision of who gets to have their light on based on the available data, possibly informed by a sensor such as an LDR.

This idea is quite a simple application of a smart system and the conceptual basis is simply that that there aren't enough resources for everyone; there are people who miss out on those that we take for granted and are accessible to us as simply as flicking a switch. This systems takes away an element of control from the user and forcing the sharing out of resources.
