Scale 1 / Electronic Scale
First thing I did was to verify if it is possible to mesure the value of a resistor with arduino. Then I did the setup that I will use in my final project wich consist in connected arduino to grasshopper via the "firefly" pluggin.
So this is the very first step of recognizing a construction kit : when I plug the small cube, the small one appear on the screen and when I plug the big one, the big cube appears on the screen.

Knowing those recognizes using resistors will work, I defined a way to connect the parts one with the others. Using a 'jack' connector (ideally with a switch included but those are expensive ...), I can expend the circuit in a serial way so knowing the previous ones, each time I add a new pieces I can recognize it by calculating the value of the resistors.
The pieces are plugged into a grid on the bottom that contain connections to the analog pin of an arduino. So each vertical lines are connected to a different pin, wich allow me to recognize the vertical parts.
Then I will have to think of an algorythm that recognize what horizontal parts did I put depending on the vertical part that I can recognize.
