WS2812FX - More Blinken for your LEDs!

This library features a variety of blinken effects for the WS2811/WS2812/NeoPixel LEDs. It is meant to be a drop-in replacement for the Adafruit NeoPixel library with additional features.

Features

• 47 different effects. And counting.
• Free of any delay()
• Tested on Arduino Nano, Uno, Micro and ESP8266.
• All effects with printable names - easy to use in user interfaces.
• FX, speed and brightness controllable on the fly.
• Ready for sound-to-light (see external trigger example)

Download, Install and Example

• Install the famous Adafruit NeoPixel library
• Download this repository.
• Extract to your Arduino libraries directory.
• Open Arduino IDE.
• Now you can choose File > Examples > WS2812FX > ...

See examples for basic usage.

In it's most simple form, here's the code to get you started!

#include <WS2812FX.h>

#define LED_COUNT 30
#define LED_PIN 12

WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  ws2812fx.init();
  ws2812fx.setBrightness(100);
  ws2812fx.setSpeed(200);
  ws2812fx.setMode(FX_MODE_RAINBOW_CYCLE);
  ws2812fx.start();
}

void loop() {
  ws2812fx.service();
}

Effects

• Static - No blinking. Just plain old static light.
• Blink - Normal blinking. 50% on/off time.
• Breath - Does the "standby-breathing" of well known i-Devices. Fixed Speed.
• Color Wipe - Lights all LEDs after each other up. Then turns them in that order off. Repeat.
• Color Wipe Random - Turns all LEDs after each other to a random color. Then starts over with another color.
• Random Color - Lights all LEDs in one random color up. Then switches them to the next random color.
• Single Dynamic - Lights every LED in a random color. Changes one random LED after the other to another random color.
• Multi Dynamic - Lights every LED in a random color. Changes all LED at the same time to new random colors.
• Rainbow - Cycles all LEDs at once through a rainbow.
• Rainbow Cycle - Cycles a rainbow over the entire string of LEDs.
• Scan - Runs a single pixel back and forth.
• Dual Scan - Runs two pixel back and forth in opposite directions.
• Fade - Fades the LEDs on and (almost) off again.
• Theater Chase - Theatre-style crawling lights. Inspired by the Adafruit examples.
• Theater Chase Rainbow - Theatre-style crawling lights with rainbow effect. Inspired by the Adafruit examples.
• Running Lights - Running lights effect with smooth sine transition.
• Twinkle - Blink several LEDs on, reset, repeat.
• Twinkle Random - Blink several LEDs in random colors on, reset, repeat.
• Twinkle Fade - Blink several LEDs on, fading out.
• Twinkle Fade Random - Blink several LEDs in random colors on, fading out.
• Sparkle - Blinks one LED at a time.
• Flash Sparkle - Lights all LEDs in the selected color. Flashes single white pixels randomly.
• Hyper Sparkle - Like flash sparkle. With more flash.
• Strobe - Classic Strobe effect.
• Strobe Rainbow - Classic Strobe effect. Cycling through the rainbow.
• Multi Strobe - Strobe effect with different strobe count and pause, controled by speed setting.
• Blink Rainbow - Classic Blink effect. Cycling through the rainbow.
• Chase White - Color running on white.
• Chase Color - White running on color.
• Chase Random - White running followed by random color.
• Chase Rainbow - White running on rainbow.
• Chase Flash - White flashes running on color.
• Chase Flash Random - White flashes running, followed by random color.
• Chase Rainbow White - Rainbow running on white.
• Chase Blackout - Black running on color.
• Chase Blackout Rainbow - Black running on rainbow.
• Color Sweep Random - Random color intruduced alternating from start and end of strip.
• Running Color - Alternating color/white pixels running.
• Running Red Blue - Alternating red/blue pixels running.
• Running Random - Random colored pixels running.
• Larson Scanner - K.I.T.T.
• Comet - Fireing comets from one end.
• Fireworks - Firework sparks.
• Fireworks Random - Random colored firework sparks.
• Merry Christmas - Alternating green/red pixels running.
• Fire Flicker - Fire flickering effect. Like in harsh wind.
• Fire Flicker (soft) - Fire flickering effect. Runs slower/softer.
