2 hex, dimension
3 program: if -> direct
Meeting 1:
After brainstorming and analyzing the given problem description, we planned to challenge the opening-closing characteristics of heliotropic field demonstrated by Karl in Digital Project. A finger structure was adopted and controlled by servo to realize the dynamics. Covered by elastic fabrics, fingers will stretch the fabric to show the opening, showing an organic plant (like flower) to open depending on how strong the sunlight is.
Meeting 2:
We made a change from 2 fingers to 3 fingers so that a hexagon unit can form, which is easily repeatable for large fields.
One "hand" of 3 fingers, powered by 1 servo with one LDR. 3 hands are located at 3 non-neighboring sides of a hexagon cell, which is controlled by an Arduino.
Programing:
Michelle and I tried "if-else" but it turned out to be more and more complicated due to the presence of threshold. By browsing the language library, a mapping function was found to perfectly match our need: to map the intensity of light to the angle of servo rotation.
