Your question implies an answer that could make sense. I am not very experienced with electronics in general, but that is the schematic. The Arduino is receiving data from CPU

It is both. About a week ago they worked together fine, but I was using headphones for the music. Then I installed the speakers and the mp3 player shield played music out of it just fine, UNLESS I added the shifty vu shield for some reason. After I installed the speakers, the shifty vu shield became incompatible with the mp3 player shield. But right now that is not my biggest concern anymore. What is a concern is that I am using a C++ program to continuously send data to the Arduino and whenever this program is running, the music (with only the mp3 player shield attached) has crazy electrical interference or something. When this program isn't sending data to the serial port, there is no problem at all and the music works fine. Not sure what this could mean.

Yes, they are using the exact same code.
Thank you for helping

Anything?

Whats can I do about this? Because they have worked together before in the past. I'm not sure why they are acting up now...

The Shifty VU Shield I think only uses the SPI pins if I connect something to it. I literally am just stacking them to see if the MP3 player shield will play sound. The shifty VU is only getting power, nothing else.

I am using the Sparkfun Mp3 Player shield and a set of speakers. In addition to this shield, I am using the Shifty VU Shield to read the audio levels so that I can synchronize some LEDs with the audio decibel levels.
Seperately, the two shields work perfectly. The Mp3 player shield, connected to the Arduino ONLY, can play the music through the speakers I've connected. The Shifty VU shield, connected to the Arduino ONLY, reads the audio levels sent by my phone via AUX cable while playing pandora.

The problem is that whenever I stack the two, the music simply stops working. I can't, for the life of me, figure out why it would do that. Everything is connected EXACTLY as they would be seperately, just stacked on top of eachother. Without even connecting the two through AUX, just stacking them, and the music stops playing.

Any ideas why?

What do you mean wrong? It has the correct name and bitrate. I dont see what else it could be? But I do see your point about it being able to load. I haven't yet, no.

Hey guys, I can't figure out why I can't hear the music being played after I load the program onto the Arduino. I am using Sparkfun's Mp3 player shield, and the library that Bill Porter created. Here's a reference http://www.billporter.info/2012/01/28/sparkfun-mp3-shield-arduino-library/. When I upload the program, I don't get any errors, but the sound simply isn't heard. I am using headphones and the headphone jack. I cleared everything off of the micro SD card except one file called "track001.mp3" just as is recommended and it's bitrate 192 kbps also (like its supposed to be). I figured if I had messed up something, the program wouldn't have compiled correctly, but it does, and it loads to the Arduino. Yet, no sound.
Any ideas here?

Can I get the COM3 (Arduino) and COM4 (PC) to talk to eachother using Arduino IDE? I haven't yet found a function that lets you mess with the COM ports. I know that if i do Serial functions i can go send a message from COM3 (Arduino) to COM4 (PC). Obviously the bluetooth chip on the Arduino is well aware of if it is paired with the PC. Why can't I access that and use it to turn on an LED?
12  Using Arduino / Programming Questions / Re: Serial commands! on: December 06, 2012, 06:57:18 pm
I'm have them connected through bluetooth. I just want an LED to tell me when they are paired, and it to turn off it i rip the dongle off the pc. In such a case, I believe I need continuous data transmission from the PC to the Arduino, but I'm not sure how to achieve this using Arduino IDE... the only way I know of to send data PC ------> Arduino is either when I'm uploading the program or when I bring up the serial monitor and type in values. In which case I can get the light to turn on as the data is sending, then it turns off again when its done.
13  Using Arduino / Programming Questions / Re: Serial commands! on: December 06, 2012, 06:47:47 pm
I am very new at Arduino guys. Basically, what I'm trying to do is turn on an LED light if the arduino and PC are paired. But it seems that "there is no way to detect the bridge, only the cars on the bridge" so I am trying to continuously send data from the PC to the Arduino and then use Serial.read() to either return -1 to turn off the light, or something other than -1 to turn on the light because it is getting data from the PC. Any ideas? Be explicit please, I'm not always seeing the big picture when it comes to Arduino. And thank you
14  Using Arduino / Programming Questions / Re: Serial commands! on: December 06, 2012, 06:36:35 pm
That's all a bit confusing. So there is no way, in an arduino sketch, to send information from the PC to the Arduino board without having to type it into the serial monitor?
15  Using Arduino / Programming Questions / Re: Serial commands! on: December 06, 2012, 06:09:28 pm
Haha, yes I'm sorry. I mean't from the PC to the Arduino. So could I write a program in C that sends data to the Arduino and then link it to the program in Arduino as a function from a library or something? How does that work?
