My first adruino board for an art project

Hello world of adruino

I've been thinking about adruino for a long time but never had a project in mind worth implementing.
I finally got an idea for an art project/sculpture that I want to construct, so I started looking into what I need for the electronics.

The sculpture will have some LEDs to self-illuminate and a speaker. I want the board to switch both on and off(speaker just needs to play one constant frequency), based on a binary pattern.

The logic is fairly straight forward and I've already written a sketch in processing to illustrate the result I want. But of course as I am a fresh starter with adruino I have a bunch of questions.

  1. Which board should I choose?
    I am sure the Uno will be able to control the LEDs, but what about the speaker? Will I need a shield like Adafruit Wave Shield for that? As I said I don't really need to play an audio file, but just a constant frequency. Plain noise will do fine as well.

  2. I want the final piece to have enough LEDs to illuminate a plexiglass objects from within (the size of a street cone), so it needs to be bright enough. I guess I could use an LED strip (or maybe a different type of light source?). I don't know much about electronics, so I am wondering if there is anything else to consider, in terms of voltage etc.

  3. Looking at the specs of Uno, it has 32 KB of flash memory. I assume that's where the software and any data will be loaded right? Or is the code loaded into the EEPROM? As I mentioned earlier, the code is fairly small (1-2kb right now in processing), but the binary data sequence I want to drive the LEDs with is more than 100kb. If I really need to load all this data, should I be looking to another board with more memory, or even an SD card slot?

thank you

I guess this video answers my question about the LED strip

That depends on what you want for sound. I would get a speaker like this Speaker - 3 Diameter - 8 Ohm 1 Watt : ID 1313 : Adafruit Industries, Unique & fun DIY electronics and kits.
The wave shield only plays WAV files and is easy to use.
You can also get MP3 shields that play MP3 files.

You can also play tones on an Arduino without any shields, just a speaker.

that's great, so I guess the UNO board on its own will do the job for what I need.
I just need to work out how to fit the data in there.
thanks
