PROBLEM STATEMENT

This spring, the Apparel Merchandising and Product Development department at the U of A will be hosting their

annual fashion show. The theme for this year’s show is ‘Futuristic Floral’ and they would like to incorporate lighted

apparel and accessories into the show.

PARAMETERS

The lighted items will use an LED and a controller to adjust the color and intensity of the light.

The LED controller will be able to determine the proximity of other controllers in order to blend colors when two garments

are near each other.
