Just over a week in and got my first cube up and running. I just downloaded the ledcube lib and someones sketch from the forums here and used it for my first test. The LEDs seem a bit dim when an entire level is lit up. I'll have to figure out if that's due to software or if I need to use different resistors. But over all I'm very happy with it so far. Kind of glad it's not perfect yet. Gives me a chance to trouble shoot it. (I live fixing problems.)
