LED Strip driving code

Here's the basic code for controlling the color of the RGB LED strip.

int RedPin = 10;

int GreenPin = 11;

int BluePin = 9;

void setColor(int red, int green, int blue)

{

analogWrite(RedPin, red);

analogWrite(GreenPin, green);

analogWrite(BluePin, blue);

}

void setup()

{

pinMode(RedPin, OUTPUT);

pinMode(GreenPin, OUTPUT);

pinMode(BluePin, OUTPUT);

Serial.begin(9600);

}

void loop()

{

for (int i=0;i<255;i++)

{

setColor(i, 0, 0);

delay (10);

}

delay(2000);

for (int i=0;i<255;i++)
