i am sorry!!!

i'm not afraid to put my time in and my skills. i coded for years making websites, vb 6.0 and making a few simple ds games.. i have soldering experience..

i may have not touched coding in a bit.. i just need some help when it comes to something new! so please don't talk down to me or treat me differently. how many of you can say you made a ds game? or made a website for a major store? or made any pc software? ok then, if you're going to teach me - then teach!

Ruffsta:
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?

Yeah it's kind of random throw of darts. If you reveal your complete target, you will see darts thrown closer to that target. You are the only one with this idea and you want US to know what YOU need, you should do better in the project description department.

Someone pointed out arduino basic tutorial will help you learn to turn on one LED. You will need a different way to do 100+ LEDs but that's where you start, if you don't know resistors yet. There are standard answers to how to control 300 LEDs with arduino but the answer will not help you. You level up first. Come back after you master the basic tutorial and someone will point you to your next step or using shift registers to do a bunch of RGB LEDs using a chip called 595 to do single colors on and off or TLC5940 and some common anode RGB LEDs for color mixing. You go from there to your final project. You want the end result now, you should post on the gigs and collaboration board to ask someone to do it for you, for some payment.

Now you bought some ebay LEDs, :slight_smile: no data sheets? Typical. Do you have the sales page, if you want some help on the LEDs and how to pick resistors?
I can't believe a dozen replies turned up between diaper change. You are really getting attention from across the globe now. Don't waste it with some negative replies.

Sergegsx:
let me ask you something?
have you paid anyone to teach you? then why should any of us feel the need to do it? all you say is "how am i supposed to learn if you dont show me"

fix your manners and then we can try to fix your arduino problem.

lets start with inputs and outputs also know as I/O
Your input....ZERO, NADA !
obviously the output is ... THE SAME.

yes, i paid a bit for php when i owned my former online mafia game..

i've tried to be nice, i have learned a few things being new to arduino.. c is definitely different than what i am used to i admit..

ok then, if you're going to teach me - then teach!

Some demonstration of willingness to learn would be appreciated.

taking a break here so i can go look at some links..

You are right I have not done that, I have done much bigger, complex and important things

ok! It was good fun :grin:

i did that when i first came here and the other forum.. kinda ran out in that dept when a bunch of people give me different bits and incomplete bits of information

a bunch of people give me different bits and incomplete bits of information

That's where experience and willingness to learn and filter come in helpful.

What "other forum" ?

ps,

never asked for anyone to "draw me up a "schematic" - but somebody could have pointed me to one that suits my project.. i haven't come across one as of yet - but hey, i'm not the one teaching am i?

have you learned about a single led and resistor yet? then take that and span it over 300 led's, your going to encounter more problems along the way but we can address them as they come up. You got to take some initiative and figure some of this out instead of carrying on this idea that someone is going to personally devote their life to hold you by the hand in every single moment of your project.

So your frustration has to do with us not having a schematic at-the-ready to post for the exact specifications you are looking for?

but hey, i'm not the one teaching am i?

There you go again with the "teaching" thing.

What do you understand by the term "forum"?

Read the datasheet for WS2803, develop your code from there.

maybe this teaches you something....GOOGLE !

https://www.google.com/search?q=rgb+led+schematic+arduino

that will be 5 dollars for the teaching leasson

CrossRoads:
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)
ws2803 for sale | eBay
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.

this was helpful, thank you.. but i was actually thinking of multiplexing them.. not sure if that's the way to go tho.

I'd suggest starting with 1, get the resistance values figured out for your particular RGB LED, get some basic code to work to understand the datasequence needed, then build up from there.
To multiplex, you will need banks of PNP transistors or P-channel MOSFETs to control the voltage to the parallel'ed LEDs.
What kind of architeture were you thinking? 'x' banks of 'y' LEDs using 'z' WS2803s?

just pm'd you about that.. :slight_smile:

Me too!!! I'm sorry, help!!!

Last summer, I bought an adjustable wrench. I want to build an engine, or a small transmission. But I don't have any clue about cars.

i'm told what i want to accomplish is not an easy thing.. how can it not be - they are just freaking bolts!!!

What he needs is not difficult - just 13 MAX7219's and 400 2-color LEDs, or 2 LEDs wired together as a 2-color LED.
Each MAX7219 driving 32 LED pairs. Piece of cake. No PWM needed.
