RGBLed Arduino library

This library for Arduino allows you to control RGB led.

Installation

Usage

Include library file header

#include <RGBLed.h>

Create an object, this object takes one parameter which corresponds to the analog pins are connected to on the Arduino.

RGBLed led(RED_PIN, GREEN_PIN, BLUE_PIN, RGBLed::COMMON_ANODE or RGBLed::COMMON_CATHODE);

Set color

led.setColor(RGBLed::RED);
// or
led.setColor(255, 0, 0);

Light off

led.off();

Set LED relative brightness level. (Note: brightness level defaults to 100.)

led.brightness(50); // 50% brightness

Set brightness and color at the same time ()

led.brightness(RGBLed::RED, 50); // 50% brightness
// or
led.brightness(255, 0, 0, 50); // 50% brightness

Flash

led.flash(RGBLed::RED, 100); // Interval 100ms
// or
led.flash(255, 0, 0, 100); // Interval 100ms

led.flash(RGBLed::RED, 250, 100); // Light on during 250ms and flash with interval (100ms)
// or
led.flash(255, 0, 0, 250, 100); // Light on during 250ms and flash with interval (100ms)

Fade In or Out

led.fadeOut(RGBLed::RED, 5, 100); // Fade out with 5 steps during 100ms
// or
led.fadeOut(255, 0, 0, 5, 100); // Fade out with 5 steps during 100ms

led.fadeIn(RGBLed::RED, 5, 100); // Fade in with 5 steps during 100ms
// or
led.fadeIn(255, 0, 0, 5, 100); // Fade in with 5 steps during 100ms

Cross Fade between two colors

// Usage: led.crossFade(rgbFrom[3], rgbTo[3], steps, duration)
led.crossFade(RGBLed::RED, RGBLed::GREEN, 5, 100);  // Fade from RED to GREEN in 5 steps during 100ms 
// or 
// Usage: led.crossFade(fromR, fromG, fromB, toR, toG, toB, steps, duration)
led.crossFade(255, 0, 0, 0, 255, 0, 5, 100);    // Fade from RED to GREEN in 5 steps during 100ms
