Just Another 3x3x3 Led Cube or call it JA3x3x3LC if you want.

But yes, for sure you are tired of this 3x3x3 Led Cubes, but... this is what I have in the Menu.

It's my first project with Arduino and I want to share it with you.

Thumbs up. Yes, I have seen several 3-cube, 5-cube and one nice 11-cube done by friends. And each is an accomplishment by its creator.  It should not stop us "mere mortals" from doing something simpler for our enjoyment! (I am thinking of doing a 1x1x1 LED cube  8))

Care to mention (not the whole code/diagram) what technique you used to control the LEDs - straight from each pin or some driver chip? On/Off or level control? Store the patterns on chip or calculate on the fly or feed from the USB (or other source)? You mention "Menu" - is there a LCD interface or ...?

I used common anode (positive) for each floor and common cathode (negative) for the 9 columns.

The animation (the 1st two of them) uses Multiplexing, the rest of the animations just runs thru the floors one at a time.

I control the cube with 4 Shift Registers (No needed really for a 3x3x3 cube as Arduino can easily handle it) but the idea is to learn how to use them, just in case I make the jump to a 5x5x5 cube hopefully RGB.

I'm going to add more info in a blog I'm making, you can get some extra info, plus a PDF as a "Guide" to make one of this.

It's not perfect, but it works, I have a lot more to learn and to improve. But it's a starting point.

Hi I just downloaded the PDF for your cube and was wondering if the shift registers are 74HC959 as stated or if they are in fact 74HC595's. It's just that I cannot find any real references to 959 's online. Is there any chance of you sharing your code as I cannot find if on your website. Nice cube and thanks for the PDF
Pedro.

Yes they are 74HC595

I thought I had corrected that error :P Going to replace the file now, but yes, you are right, they are 74HC595

Thanks, but any chance of a look at the code you did to drive the 595's ? 8)

Yes Pedro, I uploaded it to the website. It isn't the best code as I said there, but it works, and it's the first steps.

At least till I build the PCB for mounting everything and set working on the code again to make it better.

Thanks for that. I might build one of your cubes shortly and I'll let you know how I go with it, Pedro.
