Need help on RGB LED pad.

Hi all, Im new in arduino and i have alot of questionmarks in my head, I hope somebody here are willing to answer my question =).

Im just decided to make a four combined 8x8 RGB LED as my FYP. Im know nothing about this and i have 2 main problem here

  1. how to adjust the RGB light to the color i want using PWM?
  2. how to make animation (any color) to the pad?

May i know what component i need at first,and what is the prosedure?
example: an arduino board(I saw alot of arduino board in the website,which 1 is the exactly i need,Arduino Duemilanove ? ?what is the different then ?

What is the different between SPARKFUN rgb matrix pad with other brand like LEDSEE, the price is cheaper than SPARKFUN 1 alot?

Im really appreciate for those who are willing to guide me =),or give me your msn,i will add u =)

what i would like to do is just same like this video

does somebody could give me some help ? i would really appreciate it

This is a quite complex project.

If you want to control the color of each individual LED it is the same as controlling 768 individual LED's, and not just on / off .

You should start reading about multiplexing, and google "Arduino LED matrix" or "Arduino RGB LED matrix" this should give you some starting ponits.

yea,so could u tell me what knowledge or info that i needed in order to complete this,what is the procedure?so that i can go google them or find more information =) ,so far i know PWM,multiplexing is needed in this project =)

may i know what is the different between ARDUINO NANO,ARDUINO MINI,ARDUINO ATMEGA and ARGUINO DUEMILANOVE ?????

Yep, you may!!

so far i know PWM,multiplexing is needed in this project

So now you know you need them start to look them up and understand them to start with:-

You may get to a state of knowledge where you find the project is too complex or too expensive for you to do. Then again you might not. :wink:

Hey,

I too have a few questions. I just bought a serial 8x8 matrix from Sparkfun and I am looking at how to connect it via the arduino to my computer. I am a bit overwhelmed but with the right basic set of instructions I think I will be fine. I just don't want to get cavalier and burn anything out.

I just need to get things connected, and find out how to communicate with this thing from max.

Any suggestions?

I got into the led from the arduino software finally. Now I just need to learn how to send it commands from max. I started a new thread about it in the software-interfacing section.
