const int COLORLED_PIN = 6;
//Define the number of ColorLEDs daisy chained together
const int COLORLED_NUM = 1;
//Declare and initialize the ColorLED object
ColorLED strip = ColorLED(COLORLED_NUM, COLORLED_PIN);
void setup() {
// put your setup code here, to run once:
//Initial serial communication port at 9600 baud
Serial.begin(9600);
//Initialize the ColorLED class object
