Rainbow Aardvark: Part 1

I've been fiddling around some more with Arduino. Using some of their tutorials for ideas, I programmed an RGB LED to flash rainbow colors! An RGB LED is like a freak of nature. It's like an LED, but with FOUR legs instead of two and you can adjust the RGB values that go into each leg to make it a certain color. 

Also, since the LED was so bright, you can see the color more clearly reflected on the visitor's badge of my high school. See my face turning weird colors! 

Here's the code if anyone's interested: 

// sets pins for the LEDs:

const int redPin = 3;

const int greenPin = 5;

const int bluePin = 6;

const int power = 9;

void setup() {

// initialize serial:

  Serial.begin(9600);

// make the pins outputs:

  pinMode(redPin, OUTPUT); 

  pinMode(greenPin, OUTPUT); 

  pinMode(bluePin, OUTPUT); 

  pinMode(power,OUTPUT); }

void loop() {  

int red = 255;

int green = 0;

int blue = 0;

   

 for(int red = 255; red >127; red--)  

 {

 green = green++;

  analogWrite(power, HIGH);

  analogWrite(redPin, red);

  analogWrite(greenPin,green);

  delay(5);

 }

 for(int red = 127; red >0; red--)  

 {green = green++;

  analogWrite(power, HIGH);

  analogWrite(redPin, red);

  analogWrite(greenPin,green);

  delay(5);}

 for(int green= 255; green >127; green--)  

 {blue = blue++;

  analogWrite(power, HIGH);

  analogWrite(bluePin, blue);

  analogWrite(greenPin,green);

  delay(5);}

 for(int green = 127; green >0; green--)  

 {blue = blue++;

  analogWrite(power, HIGH);

  analogWrite(bluePin, blue);

  analogWrite(greenPin,green);

  delay(5);}

for(int blue= 255; blue >127; blue--)  

 { red =red++;

  analogWrite(power, HIGH);

  analogWrite(bluePin, blue);

  analogWrite(redPin,red);

  delay(5);}

 for(int blue = 127; blue >0; blue--)  

 { red =red++;

  analogWrite(power, HIGH);

  analogWrite(bluePin, blue);

  analogWrite(redPin,red);

  delay(5);}
