An Arduino class and example sketch to control an LED cube.
This software accompanies an Instructable for building an LED Cube. Read through it before proceeding.
Download the library and unzip LedCube your sketchbook/libraries folder. If the libraries folder doesn't exist already then create it first. When set up correctly you should find an example in the Arduino software under File > Examples > LedCube > ledcube.
I found a few code examples on the web for controlling an LED cube but they all required large arrays of binary or hex data to control the LEDs. I figured there must be a more user friendly way so I set out to write my own software.
I decided to make the software mirror the hardware. That meant addressing each LED by column and level rather than use raw port data or the traditional x, y, z. I also decided to start with basic functions, like turning a single light on or off, or lighting a single column, and build up from there.
There are two features which are useful for more interesting effects. One is a buffer which allows the basic functions to build up more complex patterns. The other is a sequence function which lights an array of LEDs one at a time, or all at once.
More recently I've introduced a web based UI to build up new animations in case code isn't your strong suit.
