// The LilyPad USB Plus has a built-in RGB (Red / Green / Blue) LED.
// In this activity we'll use digitalWrite to tun the three LEDs on and off
// in various combinations to create eight primary and secondary colors.

// Create integer variables for our LED pins:

// The built-in LED:

int RGB_red = 12;
int RGB_green = 13;
int RGB_blue = 14;
int RGB_yellow = 15;

// The colored LEDs along the bottom edge of the board:

int redLED = 6;
int greenLED = A7;
int blueLED = A8;
int yellowLED = A5;

void setup()
{
  // Make all of our LED pins outputs:

  pinMode(RGB_red, OUTPUT);
  pinMode(RGB_green, OUTPUT);
  pinMode(RGB_blue, OUTPUT);
  pinMode(RGB_yellow, OUTPUT);
  pinMode(redLED, OUTPUT);
  pinMode(greenLED, OUTPUT);
  pinMode(blueLED, OUTPUT);
  pinMode(yellowLED, OUTPUT);
}

void loop()
{

  // This code will step through the six primary and secondary colors, plus white and black.
  
  // For each of these colors, we'll turn the necessary RGB LEDs on or off.
  // We'll also turn on the same LEDs on the bottom edge, so you can see what's being mixed.

  // Black (all LEDs off)
