Purpose

I created this project as part of the annual science symposium in my junior year of high school. I wanted to create something that would be useful in teaching Maths and Physics. After some research, I decided to create a programmable LED Cube which would combine my interest in programming with a new experience of using hardware.

Project Overview

• The cube is made up of 64 LEDs arranged in a 4x4x4 matrix.
• The cube is programmed using Arduino Uno.
• The cube can be programmed to display various patterns like flickering, raining, etc.
• The cube can be used to display 3-D graphs, etc.
• The cube is programmed using C/C++.

Setup

• The setting up involved starting from scratch and personally soldering each layer of the Cube.
• Next step involved soldering resistors and transistors to the breadboard and linking the cube structure to the breadboard.

Program and Methods

The code has three methods that display different patterns: flicker(), randomLED(), raining()

• flicker() displays LEDs but flickers them and decreases the interval time of the flickering.
• randomLED() turns on single LED randomly
• raining() turns on LEDs from specific columns one by one

Applications

This cube can be of assistance while teaching Maths and Physics by helping in 3-D display of graphs in 3 axes, or difference between various waves, etc.
