Ok, now that we have built our 3D cube we will use this page to put up some videos of what we have programmed it to do.
Here is the first - it's a square drawing program...
The cube was being controlled by a PICAXE 28X2 module which is virtually completely self-contained and costs only £11.99 (and the programming editor is free although you'll have to but a programming cable).
We wrote the code in two steps - the first was a subroutine which would put a cube of lit LEDs of any defined size anywhere in the matrix that we chose. Then we wrote a routine which simply moved it around.
More to come...
