The most challenging thing about this board set up was the stupid gels that go over the phototransistors. These are very frustrating to get secured where they're supposed to be, but are, unfortunately, necessary for this project to work. They only let one color filter through to the phototransistor, which sends this color to the RGB LED. So, when one or more of the sensors isn't receiving light, the LED will change colors based on what each of these sensors is picking up.
