WS2812 FX Library for Arduino and ESP8266

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

• 55 different effects. And counting.
• Tested on Arduino Uno/Micro/Nano/Leonardo and ESP8266/ESP32.
• 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

You can search for WS2812FX in the Arduino IDE Library Manager or install the latest (or development) version manually:

• Install the famous Adafruit NeoPixel library (v1.1.7 or newer)
• 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();
}

More complex effects can be created by dividing your string of LEDs into segments (up to ten) and programming each segment independently. Use the setSegment() function to program each segment's mode, color, speed and direction (normal or reverse):

• setSegment(segment index, start LED, stop LED, mode, color, speed, reverse);

Note, some effects make use of more than one color (up to three) and are programmed by specifying an array of colors:

• setSegment(segment index, start LED, stop LED, mode, colors[], speed, reverse);

// divide the string of LEDs into two independent segments
uint32_t colors[] = {RED, GREEN};
ws2812fx.setSegment(0, 0,           (LED_COUNT/2)-1, FX_MODE_BLINK, colors, 1000, false);
ws2812fx.setSegment(1, LED_COUNT/2, LED_COUNT-1,     FX_MODE_BLINK, COLORS(ORANGE, PURPLE), 1000, false);

Effects

0. Static - No blinking. Just plain old static light.
1. Blink - Normal blinking. 50% on/off time.
2. Breath - Does the "standby-breathing" of well known i-Devices. Fixed Speed.
3. Color Wipe - Lights all LEDs after each other up. Then turns them in that order off. Repeat.
4. Color Wipe Inverse - Same as Color Wipe, except swaps on/off colors.
5. Color Wipe Reverse - Lights all LEDs after each other up. Then turns them in reverse order off. Repeat.
6. Color Wipe Reverse Inverse - Same as Color Wipe Reverse, except swaps on/off colors.
7. Color Wipe Random - Turns all LEDs after each other to a random color. Then starts over with another color.
8. Random Color - Lights all LEDs in one random color up. Then switches them to the next random color.
9. Single Dynamic - Lights every LED in a random color. Changes one random LED after the other to a random color.
10. Multi Dynamic - Lights every LED in a random color. Changes all LED at the same time to new random colors.
11. Rainbow - Cycles all LEDs at once through a rainbow.
12. Rainbow Cycle - Cycles a rainbow over the entire string of LEDs.
13. Scan - Runs a single pixel back and forth.
14. Dual Scan - Runs two pixel back and forth in opposite directions.
15. Fade - Fades the LEDs on and (almost) off again.
16. Theater Chase - Theatre-style crawling lights. Inspired by the Adafruit examples.
17. Theater Chase Rainbow - Theatre-style crawling lights with rainbow effect. Inspired by the Adafruit examples.
18. Running Lights - Running lights effect with smooth sine transition.

27. Strobe Rainbow - Classic Strobe effect. Cycling through the rainbow.
28. Multi Strobe - Strobe effect with different strobe count and pause, controlled by speed setting.
29. Blink Rainbow - Classic Blink effect. Cycling through the rainbow.
30. Chase White - Color running on white.
31. Chase Color - White running on color.
32. Chase Random - White running followed by random color.
33. Chase Rainbow - White running on rainbow.
34. Chase Flash - White flashes running on color.

ws2812fx's Issues

esp8266 hang and reset after running effect

Hi everyone.
I need a little help about my project
i'm using esp 8266 node mcu to control 2 button, DHT22 and ws2812 via node-red MQTT pubsubclient
the problem is my esp being hang and sometime it will reset the esp. sometime not.
i believe that the WS2112FX cause the hang.
here is my code. please help me fix it. i waste 2 days to find the problem but i fall in love with the effect of WS2812FX

Http controll

I really like your project.
But I wounder if there are any possibility to control it from external webpage with post och get function.
I´m don´t have the knowledge to figure it out.
I want to control it from a Vera home automation controller.
Thanks.

change led count in setup() or loop()

How I can change the led count in setup() or loop() void?
Thanks

Store settings after power lost

I use arduino nano with a strip ws2812b and use "serial_control". And when the power goes out, the settings are reset to the default values. How I can use EEPROM for store settings and use it for control?

Add and Remove Web Interface Buttons

As a preface, I don't have much experience with coding, and in WAY over my head with this LED programing. But I've gotten the web interface up and running, so I feel fairly accomplished already.

But how would I add a button to the web interface that would allow me to cycle through multiple effects in sequence, say for 60 seconds each. I would like to pick the effects that are included, not just all of them.

I'm also wondering how I could remove some of the effect I don't plan on using from the web interface.

Thanks in advance for the help!

Set speed inverse

The minimum and maximum are reversed, 255 = the minimum speed, if set to 1, it really puts 10 but this is the maximum speed.

WS2812FX error on compiling for ESP8266 and Arduino

Hi,

I have been trying to get your WS2812FX working with my ESP8266, but i get errors on compile ?

I am using:
name=Adafruit NeoPixel version=1.0.6
ESP8266 using Arduino 1.6.5 (Reluctant to update this as Adafruit_NeoPixel works with all my other projects)

Regards

Maybe MQTT support directly?

Since this would be geared at the IOT space it would probably make sense to support directly the MQTT protocol for setting up the lights and animations? Or at least if there was an example available for us noobs out there :D.

can we add Halloween mix!

Same as christmas but with purple and orange!
255,0,130 and 255,50,0

Add support for animation direction, and virtual strips

Okay, since the title is limited, let me explain the virtual strips part.

Say you have a few various shaped "strips", "bits", "rings", etc. made of one or more WS2812 LEDs. Say you want to control them all, but from a single pin (because your project includes more and more devices that an ESP8266 or an Arduino can support).

So it would be nice to be able to define a single strip (say, 3x 24-LED rings in series, first one connected to a pin, second one connected to first one's output, et cetera), and be able to make segments out of it, animated separately. I'm thinking something similar to this:

#include <WS2812FX.h>

#define LED_COUNT 72
#define LED_PIN 15

WS2812FX strip= WS2812FX(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);
WS2812FXSegment segment1 = strip.segment(0 ,23);
WS2812FXSegment segment2 = strip.segment(24, 47);
WS2812FXSegment segment3 = strip.segment(48, 71)

void setup() {
  strip.init();
  strip.setBrightness(255);  // Modifying the strip object will modify all segments too
  strip.setSpeed(100);
  strip.setMode(FX_MODE_FLASH_SPARKLE);

  segment2.setMode(FX_MODE_RAINBOW_CYCLE); // setting the segment options after the strip will override those settings for said segment
  segment2.setSpeed(150);

  strip.start(); // starting the strip should go over all defined segments and start them separately
}

void loop() {
  strip.service(); // servicing the strip should go over all defined segments and service them too
}

And about the direction of animations. Especially on rings, alignment is a bitch. Say you want two 24-LED rings do the same animation, and attach them back to back. Well you can't, since the directions won't match. So it would be nice if separate WS2812FX objects (and, if implemented, segments too) could have a direction set (either NORMAL, which means the current direction and addressing 0..n, and REVERSE, which means reversed direction addressing n..0).

Adapt for WS2801

I own some WS2801 and would like to control them using this awesome library.
What would be the preferred method?

1. Including support for WS2801 in WS2812FX by abstracting the Adafruit WS2801/Neopixel library calls. This would need a method to indicate that a WS2801 should be controlled, for example via a different init method.
2. Just port WS2812FX from Adafruit_NeoPixel to Adafruit-WS2801-Library in a fork (then being named WS2801FX)

Would the maintainer accept a PR that implemented 1.?
If yes, I would work on this, if not, I would attempt 2.

Help me please

Wrong color on serial control

Hi first thanks for this library was just what I was looking for but I have a problem with the hexadecimal colors, when requesting the color 0xFF0000 (red color) in the led strip this throws the color 0x00FF00 (green color), for example:

When I request 0xFF0000 -> serial print line: FF0000
When I request 0x00FF00 -> serial print line: FF00

Why is this? Why are the first two zeros removed?

thank you very much

there is an example

Platform.IO lib is invalid

It looks like platform.io library for ws2812fx is invalid, there's a subfolder and the .h file isn't in the path unless moved by hand to the right location.

New effects

You have a very good project, I'm really looking forward to new effects

problem with the file "WS2812FX.h

Hello,
I try to use your Library, but with Arduino 1.6.13,
and with Arduino : 1.6.5 (Windows 10), Carte : "Arduino Uno".
IDE arduino replies in compilation:

Perhaps, it is in this line of file " .........h" ??

Color scale on android chrome

Thank you for this wonderful library and examples. I use an example from the web server on esp. it's great.
but in the chrome browser on smartphones color scale it is not working properly.
shade similar, but very few colors.
on the PC everything is fine.
maybe you can help.

Add more realistic fire effect

The current two fire effects seem to be only based on the current color, but don't do any color variations that are typical for real flickering fire.

It would be nice, if another fire effect would be added which looks more like this one.

Plain C implementation for general MCUs

Do you have a plain C implementation of all these effects not only for arduino-compatible hardware but for general use? I mean, something, you can use with stm32 or msp430 with just C compiller and without neopixel or fastled libraries, as they seem to be useless outside arduino environment.
If no - would you like me to make such an implementation?

using your serial and web examples on nodeMCU causes an error...

I've had everything working using the basic examples you showed, but I get an error when using the serial and web examples.
When I complie using a DUO everything is fine, when I use the NodeMCU it reports an error...
section type conflict with __c
in looking into this it appears the apply() function is the issue and some definitions need to move to global and out of the function. esp8266/Arduino#2078
Is it worth addressing the problem if you are able to identify the cause?

Aircoookie branch does not compile ?

Hi,

I tried the branch version by Aircoookie but got the following on compiling.

I am using portable Arduino 1.8.0

I renamed the folder 'WS2812FX-master-fire' to keep it separate from your original.

Apologies if its something I am doing wrong.

Thanks

Remove effect simply

Hello,
How is it possible to remove effects simply?
I use "auto_mode_cycle" which is perfect for my use but there are some effects that I would not use.
Thank you for sharing
bye

Does set color have to be called at a specific point?

Using this code,

#include <WS2812FX.h>

#define LED_COUNT 4
#define LED_PIN 2

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

void setup() {
  ws2812fx.init();
  ws2812fx.setColor(255, 69, 3);
  ws2812fx.setBrightness(100);
  ws2812fx.setSpeed(70);
  ws2812fx.setMode(46);
  ws2812fx.start();
}

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

The lights seem to stay default green although they do flash briefly for a second. Am I doing this wrong to change the color?

I lack the three functions in your library.

I lack the three functions in your library.

1. Shifting the effect starts from the beginning of the tape
2. insert effect certain additional effect it.
3. Ability to share software on the tape 2, and let them alone effect it (should work with paragraph 1)

idea - grid effects!

Hi I was looking at the 3LED strings siuch as
ebay 100 x 3 led string

a hundred of these would make a nice array around .7m x 1m with 15 x 20 pixels. given you can by other volumes of these you can get a smaller or larger array.
equally you can cut up and join a 5M strip and then put end connecters to make an array.

So the interesting thing is could we run great effects on an array of lights rather than a single strip of lights? or even get a way to program a sort of moving image. (bit like the 80s with old computers and pixel graphics!)

Just a thought!
CLose this if not practical.

RGBW Support?

Hello, the Adafruit library supports RGBW LEDs but I get odd results because i cannot use the NEO_GRBW constant with your library. Should this already be supported? Or do you still have to implement it to catch up the the Adafruit library? Thanks! Your library is awesome, btw.

Big thanks!

Thank you very much for your project!
I use it in my project. If you're interested you can see here:

Calling modes and requirements for modes

Board: ESP-01S (1MB)
platformIO is used for compilation

What modes require:
Speed
Color
Brightness

to function.

When adding It doesn't power any lights on at all. Should I be calling modes by number or by name?:

 //FX_MODE_STROBE "Alexa, turn strobe lights on"
        if ( (strcmp(device_name, "strobe lights") == 0) ) {
                if (state) {
                        neopixel_state = true;
                        ws2812fx.setBrightness(BRI);
                        ws2812fx.setSpeed(200);
                        ws2812fx.setMode(26);
                } else {
                        neopixel_state = false;
                        ws2812fx.setBrightness(0);
                        ws2812fx.setMode(0);
                }
        }

Accessing "real" brightness level vs. rewriting "breath" and "fade" modes

For a specific project I'd need to access the currently set LED brightness level.
This would work fine with "getBrightness" for most effects but doesn't work when using the "breath" or "fade" effects because these effects seem to set the Neopixel libraries brightness level themselves which has no relation to the overall brightness setting (limit) which is returned by "getBrightness".

Unfortunately this library replaces the "getBrightness" function of the Neopixel library so I had to patch my version and add a "getRealBrightness" function to return the currently set brightness value.

While this is one possible solution the other would be to avoid changing the "upstream" brightness level and adjust the brightness level in both the "breath" and "fade" modes by changing the pixel colors to the proper brightness-adjusted values, similar to what is being done for example in the "twinkle fade" mode among others. This would also avoid some brightness-flickering that currently seems to occur when adjusting the brightness level (limit) while running those two modes as the change causes an immediate brightness change until the effect triggers again and sets the proper effect-matching brightness.

For the first described solution ("getRealBrightness") I could submit a pull request. However I do think the second solution might be a better approach.

New to programing

I am working on a project that uses a push button to cycle through different lighting sequences. My question is how can I take and select only the functions I want? I would like to then modify colors, timings, etc. I am sorry for the lack of knowledge, but any help would be very much appreciated.

Individual Pixel control

Would be nice to include standard method of writing to individual neo pixels in non effect mode.

Maybe there already could not see a specific function.

Problem with WS2812Fx library on Nodemcu 1.0 (ESP-12E)

Look like that the values are inverted, when i write:
...
ws2812fx.setColor(255, 255, 255);
...
the led is black. And if i set one value to 0, that color light up.

What do i wrong?

LEDs not rendering animation?

First, thank you for putting this library together. I'm trying to use it with an Adafruit tutorial for an Alexa controlled WS2812 device.

I'm going to create FauxWemo devices using the fauxmoESP library and assigning them to specific effects in your library. That way I can just have Alexa turn on/off the different effects easily.

The FauxWemo + Alexa stuff is working fine however when I try and ws2812fx.setMode(40); or any other animated effect it doesn't animate, it just sits there static. Any help would be appreciated.

Here is the code:

#include <Arduino.h>
#include <Adafruit_NeoPixel.h>
#include <ESP8266WiFi.h>
#include "fauxmoESP.h"
#include <WS2812FX.h>

Stop button do nothing.

Hello my Stop button in web interface do nothing. I would very much like it to completely disable all the effects and the tape was turned off.

control with http request

Hello,

I'm using esp8266_webinterface sketch and i'd like to control it with http request like: "http://ip_of_wemos/set?b=255" to set brightness to 255.

Is it possible ?

Issue 304.

Hi, I have a problem, because I have a strip with 492 WS2812B leds , and unfortunately I can't use whole of these leds with this library. Everything works with 304 leds or lower. When I'm trying to declare more than 304 leds my stripe is not showing anything.

`#include <WS2812FX.h>

#define LED_COUNT 492
#define LED_PIN 7

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();
}`

How can I fix this and how can I use thi library with my long stripe?
I'm looking forward to your answear.

i want to edit or add some effect

hello sir, i want to add more effects. i am using arduino but when i open auto cycle mode it doesn't show .h files how can i edit this program????

handling patterns in loop section

Hello my name is Niko
first of all thanks for sharing these information with all of us.
My request is about handling patterns in a way that can be called when a message is received.
below is an implementation that i want to achieve with nrf24.

receiver side:

#include "nRF24L01.h"
#include "RF24.h"
#include "SPI.h"
int ReceivedMessage[1] = {000};
RF24 radio(9,10);
const uint64_t pipe = 0xE6E6E6E6E6E6;

void setup(void){
radio.begin();
radio.openReadingPipe(1,pipe);
radio.startListening();
}

void loop(){

while (radio.available())
{
radio.read(ReceivedMessage, 1);

if (ReceivedMessage[0] == 1)
{do something}
if (ReceivedMessage[0] == 2)
{do something}
if (ReceivedMessage[0] == 3)
{do something}
if (ReceivedMessage[0] == 4)
{do something}

}
(run the pattern);
}

the receiver node will get these messages every 5 seconds.
So every pattern will be active for 5 seconds with its own parameters(speed and color)
in this way i can put 30 nodes which will perfectly synchronized.
If i put all nodes with one start message after a while they will not be together because of timing difference of each arduino.
And of course all these patterns need to be delay free as your library does!

thanks for reading this.

Best regards

Niko

Max number of LEDs?

Hi! First off, love this library! Just one problem I'm finding. I'm trying to control 288 LEDs, and this library seems to max out at 235. I have 2 x 1 meter strips with 144 LEDs each chained in my front window. Unfortunately, I'm not getting any use out of those last 53 lights. Other libraries like FastLED and Adafruit Neopixel seem to work just fine, but I really love the FX in this library. The strips are WS2812B running off an Arduino Uno R3. Should it be possible to control all 288? If so, any ideas on what I might try to get this library to work with all my lights? If not, just curious why and if there's a chance the limit could be raised. Thank you very much for the hard work on this!

REDUCED_MODES not working?

Using my Arduino Micro to control my WS2812b ring and the sketch size is just too big for it so I added #define REDUCED_MODES thinking it can shrink the sketch size, but before and after adding it, the sketch size does not shrink but remain the same size. Also I only want a certain effects, can I add more effects I wish to be replaced with STATIC into the library?

speed calculation

Hi!

look like speed calculation wrong (IMHO)
can you change speed calculation like this:

//SEGMENT_RUNTIME.next_time = now + max(delay, 20);
SEGMENT_RUNTIME.next_time = now + map(delay, 0, 255, 20, 1000);

Thank you!

Hi,

I had a arduino ATMega328P code compiling with this library (SHA 069139b). Code size was 29948 bytes. If I compile same code with latest, code size blows to 38694 bytes.

The newer commits added about 8KB of code, this represents 1/3 of available code memory for an regular Arduino.

Only 19 LED's of 144 working

Hi, firstly I am new here! So please be patient.

Using sample code sketch on a 144LED Strip - http://www.banggood.com/5V-WS2812B-43W-144-SMD-5050-RGB-LED-Strip-Waterproof-IP65-Individual-Addressable-p-1042712.html and only 19 of the LED's are being used.

Tried the Adafruit NeoPixel Library and made no difference?

Any suggestions?

#define LED_COUNT 144
#define LED_PIN 11
WS2812FX ws2812fx = WS2812FX(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

MSGEQ7 support

For "music visualisation"/ "spectrum analyzer" effects, the MSGEQ7 is a great chip, there are quite a few examples on youtube. It would make your library more complete if you would support it.
