My arduino plays the music

but no music is working

Those two statement appear to contradict each other. Pretend like we have no idea what your project is supposed to do and try explaining what you're expecting it to do, and what it is actually doing, without using the phrase "it's not working".

Also, post code with CODE tags, not QUOTE tags.

Add a start() or begin() method that can return an error.

34  Using Arduino / Programming Questions / Re: my if statements keep repeating themselves on: September 16, 2013, 09:19:58 pm
Code:
  if (buttonStateOne == LOW){
    ...
    if(buttonStateOne == LOW){
     lcd.clear();
    }

Why bother checking again? You never update buttonStateOne between the two if statements, so the second one will ALWAYS run.

Based on your usage of the variable, I'm guessing readString is a String and not a string? In that case, you need to convert it to a string first, or use whatever method is available for the String object to do the conversion.

One works and the other one doesn't.

So im using my router ip and 192.168.2.1:5566 and accessing

That's still a local address. If port forwarding was working, you should be able to access it from the external address. Once port forwarding is enabled on the router, visit www.canyouseeme.org/ and check the port number. If it tells you no, then your ISP might be blocking that port.

You could build a custom core that "remaps" those pins.

Now run it through the Auto Format tool (Ctrl + T in the IDE) and re-post it to fix the indenting.

Start by posting ALL of the code PROPERLY and maybe we can help.

All that picture shows is that you've soldered wires to the three leads; it gives no information on where they are going. Try making a wiring diagram in something like Fritzing and stop bumping your threads after an hour without a response; have a little more patience than that.
42  Using Arduino / Programming Questions / Re: Writing "if" stament correctly and other functions. on: September 14, 2013, 10:18:14 pm
I assume when you say "code" you mean the literal command "code", so block together lines between delays with code 0, code 1, code 2, ect...

There is no "literal code command"

Generally from the Arduino's ground to the power source's ground.
44  Using Arduino / Programming Questions / Re: Can I use an array of strings to call on an array? on: September 14, 2013, 04:27:05 pm
to be able to get a value from an array using an array of values to do so.

You'll have to further explain what you mean by this. How is this "array of values" supposed to map to a single number in an array?

Ditch to "Copy to forum" function and just paste the code in regularly.
