i am sorry!!!

I'm sorry your present skills and knowledge don't allow you to transform your idea into a real product by yourself, but again just learn the basic skills first before building your project, or share what information is required for someone to be able to help you. I don't get what your expectations are?

now, if i were to say that 4 grids would have to be made the same exact way and they would all have to work together.. then i could see someone say that was a difficult thing to do.

trying to accomplish exactly this: i cannot explain it any better

1.) 100 rgb leds
2.) 100 instances that light up 17 leds per instance (based on a users choice)

ex: if user selected "1", then a certain 17 leds would light up out of the 100 (some will be different shades of green), green will turn into red as needed - but that's important atm but the shades of green are.

the user will pick the instance through a 4 digit led (with 3 buttons.. up, down and set) ignore the set button atm.. the leds will light accordingly to the last 3 digits of the 4 digit led.. the first digit will be used as a letter. and we are not really even talking about the digit led.. except that the instance 1-100 will be select through it.

is that so hard? yet any help i have gotten, nobody has shown me the exact parts to get, nor any exact coding.. just thoughts

is that so hard?

No, it is very, very simple.

Now you need to tell us how these 300 LEDs are wired and what resources they use.

100 RGB LEDs, you can control 6 each with WS2803 with full color fade control, just need 17 chips if you don't want to muliplex them.

Available on e-bay (only place I've seen them in fact)

and only from 1 place in Niagara Falls, NY

Have read that WS2801 library is similar to what's needed for WS2803.

Or just wire up a chain of 100 of WS2801, and send out the 100 pieces of information needed for each RGB LEDs color based on your user input.

If you need things like, coding for a simple project that is less than 100 lines of code, I might just type it up and post it here. What you need is around 300 lines of code. Nobody in their right mind will give you an exact code, since you don't say how things will happen exactly (your million dollar secret that everyone is going to steal). Nothing was said about how these LEDs will be wired, critical to coding. You are not just asking for a program, you are asking the whole thing. There is nothing simple about this idea you have. If you want some paid help, post on the gigs and collaborations board and pick someone you can trust. Lefty spelled out clearly what free help gets you. If I were Massimo, I'd be unwilling to help. There are plenty of people with their big ideas asking him I suppose so what's so different with your case?

What you need is paid help with NDA.

this is what i was told once: on adafruit forum

Starting with discrete RGB leds, you are looking at 100 RGB leds, 300 resistors, and 300 I/O pins to drive them. The leds and resistors are straightforward enough. 300 I/O pins is a little more involved. The Arduino has 20. The Mega still only 69. You will need some port expanders like the MCP23017. You can chain up to 8 of these on an i2c bus for 128 pins. Using 'softI2C, you can create multiple i@c busses to get beyond that.

There is no easy answer to your question

i don't know if they think everyone knows as much as they do or what.

There is no easy answer to your question

That's complete nonsense.
There are many easy answers.
One involves a machine with 300 PWM resources.

not asking for everything.. i just want to have some kind of schematic that's good for my project, show me the exact parts and how many i need.. show me some kind of exact coding.. yes 100 leds is a lot, but if i were shown say 10 i could do the rest.. give me some real help with my project... i mean really

Are you really expecting someone to draw up a schematic and write the code for you for free, and anything less isn't "help"?

Wow... what has this world come to...

300 resistors, and 300 I/O pins

show me the parts, which resistors which i/o pins.. i don't know what they are..

I mean, really!

Arrch:

no, but damn give me something to work with..

what do you really need?
a list of the parts required to build the project? CrossRoads has helped you with that
a description on how to connect the leds? well CrossRoads did give you the information, not the solution, but the location on where to find it. now its your turn.
the code for your project? visit my last two links, will point you to websites were people charge you for working for you. thats what you need.

The forum will give you hints on how to accomplish your project, but dont expect someone to sit down and make the project for you. and if so, where is the fun here? you wouldnt have learned anything.
Stop complaining and do some research on CrossRoads suggestions.
build a small project with fewer leds, say 10,then 20, then 50 and post your progress here, and your code and keep expanding.
you need to put some work in this, dont expect everything being done for you.

then start with this...

Good luck with your pursuit. As you show no attempt at learning the basics like most of us, you will most likely find that your expectations exceed your grasp.

no, but damn give me something to work with..

wow, does everybody take things the wrong way and/or turn things around?

i'm told all sorts of different things..

one tells me i need i/o pins, the other tells me there is no easy way of doing it, another throws code at me that i have never seen before and no explanation... another one tells me things to get but doesn't show me exactly what they are.. and i'm supposed to learn?

i'm supposed to learn?

Bingo!

Edit: Do you want me to move this to "Gigs and collaborations"?

Ruffsta:
and i'm supposed to learn?

Yes, that's the point.

You seem to expect nothing less than a complete project explanation with schematics and code.
