5x5x5 LED Cube – Orientation Independent 3D Display

Introduction   Our project, in one sentence, is an orientation independent 3D LED display. We were inspired by various videos on youtube of similar cubes but also by the idea of creating an interactive 3-dimensional display. We built a 5x5x5 LED cube display and controller board which interfaced the cube to a Mega32 microcontroller. We can display a wide range of low resolution 3D images or animations ...
