Ok I have two projects in mind, but I figured I would start asking for some info for, what I hope, is the easier one. Note that I know these are high level questions for now, and I will be investigating on my own, but any tips or pointers would be great (i.e. I don't expect you to do all the work for me ;))
The idea is to make some "lightning bug" led modules. I have two large olive trees in my back yard and would like to be able to put some lights in them all spread out. Then I would like to be able to update their behavior from time to time.
I realize I could just buy something like the BlipTronics LED Modules but what is the fun (and learning) in that? :) Plus they are too close together as-is.
So the questions I have are: 1. What is a good way to power these? I think there are going to be more than the Arduino can handle itself. I can run wire to an outlet, but would also like to consider a solar rechargeable battery setup. 2. If I go with RGB LEDs and would like to be able to have each LED be an independent color (or timing) will multiplexing work ok? -or- 3. Would it be better to build some hardware into each LED module to be able to communicate with each LED (similar to the BlipTronics)?
I am new to the hardware, but am very comfortable with the software side of things.
