I am kind of in the same boat as some others in here, but I didn't want to hijack someone else's thread.
For my first "project" I have a number of components that all need addressing. The first part of that is probably the most hindering on what board I need to get.
I really want to be able to build a fairly large LED matrix, either using pvc piping to shield each individual LED or ping pong balls.
Something in the range of 10x20 or perhaps a little bigger or slightly smaller. The point being I don't only need an 8x8, and I would prefer not to have to use an external chip to address the led's, but if it's a $10 shield add on and it makes my job easier, I am fine with that.
In regards to that, is the power provided to an arduino enough to power that many LED's? So how does one power that many LED's?
I have looked at the rainbowduino, and the lightuino, but I am not sure if those are overkill, or exactly what I need, or they are missing other features I need.
I have also seen some RGB led's that would be nice to use. As I understand it, that would mean I would need 4 wires in some form or fashion going to every LED, in a matrix.
If my math is correct that means at minimum 50 output connections. 10 to red, 10 to green, 10 to blue and then 20 in the other direction.
The other features I am looking for, is the ability to do some motion sensing and/or light sensing, but that's probably the easiest part, since from what I understand at most that would take 3 analog inputs.
In regards to that what would be the best method to make a simple object sensing. Similar to a ball going into a basketball hoop toy game counter of some sort. I was thinking light beam break, but since the I am not sure how sensitive that would be it might not work.
The last component, which can come later is the ability to run a web server either via wifi or ethernet to control the arduino. I can add an ethernet shield later on, but I would like to know which if any specific one supports basic web server and backend scripting with the ability to control the arduino directly.
I am new to this for sure, but I am fairly confident in my ability to learn, and create something, but I just don't want to spend $50 and then find out I needed to spend another $60 to get the features I needed.
The seeduino mega seems like the ticket, has 70 i/o points, so it would give me room to grow. Any help is appreciated.
