The 3D LED Cube is a really cool device that enables you to see in three dimensions, get some depth perception and has 512 LED's or 512 pixels. It is based on an arduino uno which is an Atmel AVR microcontroller on a development board with some standard interfacing pinouts that allow you to quickly assemble prototypes. Since Arduino has only 13 digital output pins we have used shift register named and marketed as 74HC595 IC this IC helps us to multiplex its pins to control 512 LEDs independently. Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world.
