Updates to the Christmas tree project

I made a handful of modifications to my Christmas tree this week! Using shift registers I eliminated most of the wires connecting the Arduino to the LED display. Programmed a few scrolling patterns and select between them randomly. And I neatened up the wiring a little bit, so the whole thing is not quite so ugly.




Seems to be a couple deficiencies though... I think its due to the way I tied the shift and latch clocks together, but I am not able to get the top row of my tree to light up. And I would love to make it battery powered and wireless and hang it on my actual tree. Might be a bit ambitious for now though, and would require taking apart one of my older projects which I don't know if I want to do yet.
