Check out this project.  Does exactly what you want, no PC needed.
Basically it makes a noise when the distance sensor changes dramatically.
Parts used.
Arduino Uno
WAV shield
SD card
Sharp distance sensor
Stuffed sheep

You problem seems to be getting your data out of the  Arduino over Serial.
With a program called Processing you can save data to a text file.
If you have a PC some folks use a program called Gobetweeno.

I would use this data logging shield.  No PC needed.
Here is the tutorial on how to use it.

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?
That depends on what you want for sound.   I would get a speaker like this
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.

This page also has some great ideas.

    Blink an LED
    Send Morse Code
    Fade an LED
    Using the MakerShield – Button
    Make Music
    Build a Pitch Follower (Theremin-Like Noise Maker)
    Control a Servo with a Potentiometer
    Make an LCD Shield
    Control a DC Motor
    Make an RGB LED Lamp
    Control a Servo with Touch

My guess is you are running out of memory.
I always put any serial print statements like this with the F.  The text is stored in flash memory in stead of SRAM.
Serial.println(F("This string will be stored in flash memory"));
22  Using Arduino / Project Guidance / Re: "Sshhh" button. on: February 20, 2014, 04:16:40 pm
Well, I see you as needing 4 more items.
1. Arduino (I suggest an Uno)
2. Speaker like this one.
3. A button like this
4. A power supply.

For Software, look at Adafruit examples.
23  Using Arduino / Project Guidance / Re: Beginner. on: February 19, 2014, 04:33:17 pm
Here is another starter kit.
Adafruit also has some great tutorials.
24  Using Arduino / Project Guidance / Re: Photo resistor as on/off switch on: February 19, 2014, 11:43:02 am
I would use a distance sensor like this one from Pololu.
That way, when someone is within a certain distance you your project, it ca turn on.
25  Using Arduino / Project Guidance / Re: Connecting to Twitter? on: February 17, 2014, 06:23:36 am
I tried connecting to Twitter a long while ago, then they changed there authentication method and I gave up.

Someone here is using a program called Growl as a way to get notified via SMS
26  Using Arduino / Project Guidance / Re: RFID Doorlock with LCD. CODE AND SCHEMATIC NEEDED. I WILL PAY FOR IT. on: February 17, 2014, 06:03:05 am
If you are willing to pay for a schematic and code, I would make a post in Gigs and Collaborations.
27  Using Arduino / Project Guidance / Re: Finalizing project on: February 15, 2014, 09:58:53 pm
Here is an example of a standalone board.
28  Using Arduino / Project Guidance / Re: RFID Doorlock with LCD (Optional: Keypad) on: February 15, 2014, 07:34:43 pm
Do you have a link the RFID reader you bought or the datasheet?
29  Using Arduino / Project Guidance / Re: Replacing the Arduino in project with other components on: February 15, 2014, 05:03:56 pm
As crOsh says, you can do a stand alone Arduino.
I bought enough components to make 10 of them as some parts are cheaper if you buy 10 or more.
See what I did here -
Basically I ended up with a $13 - $14 Arduino instead of a more expensive one.
30  Using Arduino / Project Guidance / Re: RFID Doorlock with LCD (Optional: Keypad) on: February 15, 2014, 04:54:39 pm
I tried the RFID reader from Adafruit a while back.
They have some good documentation about it here -

I found this website with info about the RFID-RC522 - , they have some documentation and sample code here -

 Pin connection

Pin layout should be as follows (on Arduino Uno):

    MOSI: Pin 11 / ICSP-4
    MISO: Pin 12 / ICSP-1
    SCK: Pin 13 / ISCP-3
    SS: Pin 10 (Configurable)
    RST: Pin 9 (Configurable)

This should get you started.
