Dot matrix display? I'd like to make one I know that much. There's 3d cubes that can form patterns and everything, and there's an instructable one how to make one, I don't know if you're interested but it looks hell cool!

Well, using a (bunch of) decade counter(s) or some other counter type IC is actually more complicated. You would be hardwiring the sequences rather then simply transferring a bit of code to the micro

Put them in a panel and create a processor that generates random patterns. Wire them to your halloween masks.

Unfortunately, 100 LEDs in a matrix (10x10) isn't really very many. I've been working with this 16x24 Led matrix (384 LEDs!), and it's still pretty difficult to do any pretty graphics on it (for instance, "life" is quite limited.)


BTW, it's a pretty cheap ($16) display and interfaces nicely to an Arduino. (as shown above)

Ghee, that's really good! I like the second thingy, but if you could make it slower it would look a bit more impressive and less confusing. Good on ya!

A count-down to christmas or other holiday starting at one-hundred days away. You could make it have an automatic controller that shuts off an LED every 24 hours. Maybe?

This is a great idea, and well within "beginner" capabilities, I think, especially if you're willing to do it "Dig button" style, and push a button for each new day (in fact, a Digg Button might be a good starting point to avoid having to make your own PCB. If you don't get to re-writing the SW (to count down instead of up), you'd just end up with a giant Digg Button...

I'm not sure what do with the two colors; are these two-lead or three-lead LEDSs, and how bright?
