March Madness Challenge - Day 6

Loss of brain power leads to coding RGB LED enumeration for Arduino. Tired going to bed soon.

int redPin = 9;    // LED connected to digital pin 9
int greenPin = 10;
int bluePin = 11;

void fadeIn(int pin, int fadeInc, int delayValue)
{
  for (int fadeValue = 0; fadeValue<= 255; fadeValue += fadeInc)
  {
    analogWrite(pin, fadeValue);
    delay(delayValue); 
  }
}

// fade out from max to min in increments
void fadeOut(int pin, int fadeInc, int delayValue)
{
  for (int fadeValue = 255; fadeValue >= 0; fadeValue -= fadeInc)
  {
    analogWrite(pin, fadeValue);
    delay(delayValue); 
  }
}

void rgb (int r, int g, int b) 
{
     analogWrite(redPin, r);
     analogWrite(greenPin, g);
     analogWrite(bluePin, b);
     delay(30);
}

void setup()  { 
  Serial.begin(9600);
  
  // diagnostic lights on
  fadeIn(redPin, 5, 60);
  fadeOut(redPin, 5, 60);
  analogWrite(redPin, 0);
  delay(30);
  fadeIn(greenPin, 5, 60);
  fadeOut(greenPin, 5, 60);
  analogWrite(greenPin, 0);
  delay(30);
  fadeIn(bluePin, 5, 60);
  fadeOut(bluePin, 5, 60);
  analogWrite(bluePin, 0);
  delay(30);
  Serial.print(redPin);
  Serial.print(", ");
  Serial.print(greenPin);
  Serial.print(", ");
  Serial.println(bluePin);

} 


void loop()  {
  for (int r = 0; r <= 255; r++)
  {
    for (int g = 0; g <= 255; g++)
    {
      for (int b = 0; b <= 255; b++)
      {
        rgb(r, g, b);
        Serial.print(r);
        Serial.print(", ");
        Serial.print(g);
        Serial.print(", ");
        Serial.println(b);
