Hello everyone!
Before I start properly,
XD I just had to test this out XD
Anyway, back to the point...
I've finally completed a project that I started some time back.
As the title hints, it is a 3X3X3 LED cube. Using 27 LEDs, it creates
some cool patterns and effects. I used two codes for this project.
The first one was boring, so I re-wrote it to be much more exciting.
Now, it is 8 pages long (size 11 on word), 359 lines long, and 6246
characters. This means that I will have to keep the description
brief to fit in everything.
The code is here:
int Abrightness = 0;
int Bbrightness = 0;
int Cbrightness = 0;
int brightness = 0;
int LED;
int layer;
int pin;
int func;
//pin declerations:
//verticle coloumbs:
#define axay 53
#define axby 52
#define axcy 51
#define bxay 46
#define bxby 47
#define bxcy 45
#define cxay 41
#define cxby 40
#define cxcy 39
//horisontal layers:
const int layerA = 9;
const int layerB = 8;
const int layerC = 10;
/* A note for pin names:
All the pins use the XY graphing formation, hence the second letter being
an x and the last being a y. Having numbers in the pin decleration confuses
it though, so the number 1 has been replaced with the letter A, the number 2
has been replaced with the letter B and the number 3 has been replaced with the
letter C. The bottom layer is layer a, the middle is bottom b and the top layer is
layer c. (The LEDs in each layer are arranged like this:
axcy bxcy cxcy
axby bxby cxby
axay bxay cxay
)

I wrote all of the second code in a night or two. The hardware took a couple
of nights to complete, but I ended up doing several projects in between
building the hardware and writing the new software, so it was a month
or two between starting and finnishing.
Here is a video to show everything:
The cube uses 5 functions, all written in the software, then randomly selects one
to create lots of interesting effects. As it is only a small cube, it uses no
multiplexers and can be controlled from the duemillanove, uno, or something
similar. Now, I wonder why I used the mega instead. Ah well...
Hope you like it!
Onions.
