Week 9


     The code only simulates the changing colors as it did last week, and will be illuminated separately. This code will be used to program a set of red, blue, and green LEDs with a set of white LEDs which will dilute the colors. This code will simulate daylight by changing the length of time that the colors cycle through to a full day.
     Because the code is finished, the group primarily worked with DIALux today. Trevor and John simulated the room so that the ceiling is implemented with skylights, and the noontime sun is shining through the holes. This will mimic the finalized room, as the lights will display the same colors and brightness as the sun.

DIALux simulation of the room with the walls oriented correctly with the sun at noontime.

     The simulated room has three windows: one visible on the back-left wall, and two unseen on the front-left wall. The other nine light spots in the room will be created with the light fixtures, but are simulated as skylights.
     We took screenshots of the room in half-hour increments over the course of a day, which displays the way that the light intensity will change. We will combine this simulation of intensity with the MATLAB simulation of color to create a lighting fixture which will change in both color and intensity.

     The group will meet this week to finish the simulation and work on the final report and presentation.
