Design and Construction of A 16×16×16 RGB Led Cube Display

The paper presents the design and construction of a   RGB (Red-Green-Blue) Light Emitting Diode (LED) cube display. The entire hardware structure consists of 4,096 RGB LEDs formed three-dimensionally that displays the spectrogram animation of a music file. This engineering piece achieves its effect using PIC18F4620 and PIC18F2620 microcontrollers for the controller circuit and FFT algorithm respectively. Its design also includes integrated chips (ICs) such as ULN2803 driver sink, 4514 multiplexers, shift registers, ISD 17240 voice chip, and the WTV020 music chip to accomplish the seamless 3D animation of a music file in a fast-changing 3D pattern/shapes that produces a clear fanciful illusion of the spectrogram of sound.
