So your looking for voice recognition? There are VR shields you can buy online. Look into EasyVR.

You will need at least 6V to get it to turn on, and about 7V for perfect function.

This should have everything you need. http://arduino.cc/forum/index.php/topic,140459.0.html

I would use 2 map functions, one for the servo and the other for the LED. Don't use the same variable for the output of the maps.

Code:

void loop() {
   val = analogRead(potpin);
  int LED = map(val, 0, 1024, 0, 255);
  int SERVO = map(val, 0, 1024, 0, 179);
  myservo.write(SERVO);
  analogWrite(ledpin,LED);
  delay(20);
}

Try this

Do you have a schematic?

If you bought it from Ebay, then the seller should have provided you with the libraries, or at least tell you where to get them.

[without]

Your going to need a timer for one, and two, you might run into problems with

1. Press one click to on and one click to of

and

3. Press continuously to change the brightness up and down.

Being that you said you have poor programming knowledge, I suggest you get a C/C++ basic programming book and take a look at the "Blink without delay" example.

You can't communicate to the BT module with the serial monitor. You need to use Putty.

Check your data sheet, you may have at least 2 pin available. If so, you can use soft serial.

[into a keystroke]

I need to write a code that would send a serial over when I press a button to either c# or c++ that would read it and then transfer that into a keystroke

It sounds like you are going to need a Leonardo, not an UNO.

Are these

const int xPin = 0;
const int yPin = 1;

on the digital side or analog side. There is a difference. If they are analog, then rename them to A0 and A1 and try that.

Also you should include Serial.println() after Serial.print(yValue);

Code?

It appears that this library can not print text. Im looking at the .h file and it looks like it is just for simple boxes and lines.

It should have came with a demo, does that print text on the screen?

Could you post your code and .h file?

Post your code and make sure the BT module is NOT connected to the Tx/Rx pins when you upload your sketch. Also you cannot communicate to the BT module with the serial monitor, use Putty.
