Overview
Our mini sculpture concept, the colors sensing pathways, involves using a touch sensor to sort marbles down two different tracks based on the user's choice. Alternatively, a color sensor will sort the yellow and red marbles onto designated tracks. A motor either allows the marble to fall down into a funnel or moves it onto a separate, slower track. Both ways lead to the same return system which brings the marbles back up to the top of the structure.

One issue was with getting the color sensor to read precise and accurate values while taking into account the ambient lighting. This required fine tuning with the color values in the code, as well as coloring the marbles with distinct colors so the sensor would have an easier time distinguishing them.
We also had issues with the marbles being piled up at the stop in front of the sensor, causing them to all fall at once without being analyzed first. In order to stagger them more, in the return system we spaced out the marble carriers so that only a certain amount of marbles could be at the top of the structure at the same time.
