Port port1 (3,4,5);

}

This is the code I have written. It is just an object to keep track of which pin is which on multiple RGB LEDs. The error I get is error: 'Port' has not been declared. The line it gives for the error is a blank line. Any ideas?

Stop trying to implement your class (poorly) in the same file you declare the class in. This is NOT C#!

he error I get is error: 'Port' has not been declared

The error I get is "undefined reference to loop"

class Port{
  private:
    const uint8_t redPin, greenPin, bluePin;
  public:
    uint8_t getRed(){return redPin;}
    uint8_t getGreen(){return greenPin;}
    uint8_t getBlue(){return bluePin;}
   
   Port(uint8_t redPin, uint8_t greenPin, uint8_t bluePin) :
     red(redPin), green (greenPin), blue (bluePin)
   {  }
};

Port port1 (3,4,5);

void setup()
{
}

void loop ()
{
}

Interesting. Using 1.0.5, I get something completely different. Changing the constructor so that it stores the arguments into the fields, as so:

   Port(uint8_t red, uint8_t green, uint8_t blue) :
     redPin(red), greenPin (green), bluePin (blue)
   {  }

I get:

Binary sketch size: 522 bytes (of a 32,256 byte maximum)

which is the 'error" most people try to get.

class Port{
  private:
    const uint8_t redPin, greenPin, bluePin;
  public:
    uint8_t getRed(){return redPin;}
    uint8_t getGreen(){return greenPin;}
    uint8_t getBlue(){return bluePin;}
   
   Port(uint8_t redPin, uint8_t greenPin, uint8_t bluePin) :
     red(redPin), green (greenPin), blue (bluePin)
   {  }

This still won't work, because the class variables you defined on the third line, have DIFFERENT NAMES to what you are assigning in the constructor.

You need to start looking at the error messages from the first one, not the last one.
