	RGBLED.h - Library for controlling an RGB LED
	Created by Bret Stateham, November 13, 2014
	Released into the public domain
	You can get the latest version from http://github.com/BretStateham/rgbled

	To create an instance, call the RGBLED constructor with the red, green, and blue pins, as well as the type, COMMON_CATHODE or COMMON_ANODE

	There are two basic types of RGB leds, COMMON_CATHODE and COMMON_ANODE:
	COMMON_CATHODE RGB LEDs have a common cathode "leg" that should be connected to ground (GND) arduino
	COMMON_ANODE RGB LEDs have a common anode "leg" that should be connected to 5V on the arduino

	You need to physically connect the RGB LED's Red, Green and Blue pins to Pulse Width Modulation (PWM) capable pins on the Arduino
	On the Arduino, digital pins 3,5,6,9,10 & 11 are PWM pins as indicated by the "~" infront of their pin numbers on the board

	Create an RGBLED instance by passing the red, green, blue and type (COMMON_CATHODE or COMMON_ANODE) into the constructor.
	
	For example, the following code would create an RGBLED instance named rgbLED for a COMMON_ANODE RGB LEDs with the red, green and blue 
	legs connected to 11,9 & 6 respectively:

	RGBLED rgbLed(11,9,6,COMMON_ANODE);

	You can then call then various methods on the RGBLED instance:

	writeRGB(red,green,blue);
	writeRed(red);
	writeGreen(green);
	writeBlue(blue);
	randomColor();
	turnOff();
	mapValue();
