Week 3: Color Music
The team spent most of week three waiting for the ordered parts to arrive. In the mean time, further research was conducted in order to plan what the functioning of the LED lights would be characterized by. Each member conducted research on a certain aspect and relayed that information to the group.
Research was done on "chromatherapy" and general color psychology in order to determine how colors affect human emotions. This research was meant to avoid arbitrary assignments of a certain color to a certain frequency.
This circuit was set up using two RGB LEDs powered by two 1.5 volt AA batteries connected in series. These LEDs each have one common cathode, and an anode for each color (red, blue, and green). The cathodes of each of these LEDs are connected to the positive end of the battery, and the anodes are wired together and connected to a push button so that pressing one of the three buttons allows the LEDs to illuminate in one of the colors. The video demonstrates these lights operating without resistors, which will be included in the final project to balance out the intensities and aid in color mixing. The colors can mix fairly well with these buttons, but when powered by an Arduino they capable of adjusting to nearly any shade.
Finally, research was conducted on music equalizers and how they are altered for each genre of music. The team learned that each equalizer was separated into bandwidths, just like the Spectrum Shield separates sound, and the frequencies with the highest intensities are lowered whilst those with lower intensities are increased to allow the listener to hear each bandwidth. This basic theory has been generalized to create equalizers that fit specific genres of music based on the frequencies of the instruments used in that particular genre.
