Makes sense! The client will call the callback.

Next time I'll make sure to drink some more coffee so I do not overlook that hahah ... 😉

Hello and sorry for beeing so long not here! O_o

Now my 3rd attempt to write here. this constant SPAM suspicion is annoying!

I had something to do in life and yesterday my hardware finally arrived, the "WeMos 1 mini".

After soldering and the first idle test, I naturally copied the sketch directly onto the small one. After a greeting in the chat (as intended) nothing worked anymore. Just boot loop.

I then looked for some tips and tricks and tried them out. Now I came to the conclusion, with smaller sketches runs without boot loop, so I start again and lo and behold :) now no more boot loop and he also answers in chat as requested. Apparently it doesn't control the LEDs.

first of all my current newly composed sketch and of course the question

what could be the reason or how to test without neopixel? ;)

I admit, I didn't buy an original Neopixel, but a broken Grundig light with 81 LEDs, (ebay /itm/394444649264)

which otherwise has some of the Neopixel effects and the LED strips also have 3 pins

[- Data +] with another original controller all of the Grundig is working.

how can I find out if they are even suitable ?

Sorry!!!!

I measured on the Grundig light, there are always 5V on the data line
[ +5V | Data (+5V) | GND ]

and with the WeMos apparently nothing at Pin D6 ... does it have to be like that?

But the WeMos has pin D4 for an external LED no matter how i try to map it.

Now my 3rd attempt to write here. this constant SPAM suspicion is annoying!

I'm sorry for the inconvenience - that is indeed super annoying 😞 
Unfortunately, the amount of spammers is getting worse and worse by the day, and the protection tools/services will never be perfect.

Optionally you can attach the INO file - not sure what happened with the code either haha. (will take a look after posting this reply)

Interesting, that is not what I would expect?
I'd expect to see only 5V "peaks" when data is being uploaded.
The rest of the time I'd expect it to be 0V (I think the typical spec of 5V LED strips say something like < 0.7V, but I could be wrong).

Hurra!! Hurraaa!   I´m a lil stupid :D :D :D

I´ve forgotten 1 Line in the new Sketch in the "void setup()" part...

FastLED.addLeds<WS2811, PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );

Now its working, but every effect freeze after a few seconds and fire shows almost nothing or only 1 Led.

WhoooHooooo!!!!

here my nearly complete Sketch ;)

only the Bouncing Ball Effects seems not working correct.

and maybe each effect only active for ~30 secs. but not the single colors...

a lil more work is waiting ;)

for the moment - many many thanks to @hans

yes. the Grundig seems never turned really OFF, only no effects ^^

Yes, many thanks to you @hans, it's going so far.

 

ToDo List:

• the fine-tuning for the effects that cause the Wemos to crash

• Set all effects to a certain duration (20-30 sec.)

• Brightness by command? the default doesn't seem to work... "#define BRIGHTNESS 100"

• Is it possible to adjust the Rainbow Glitter (Neopixel) for this?

• Is it possible to additionally set a VU meter as a selectable effect?

• maybe later versions for Websocket? so users can unlock the effects with channel points

• and an adapted version for serial monitor, without WiFi... ... ...

Tip for brightness, if I recall correctly (documentation);

byte brightness = 255; // 255 = max brightness, 0 = off

...

FastLED.setBrightness(brightness);

You may need to do a 

leds.show();

to make it visible.

Thanks very much!!!
what a shame O_o i think i´ve never read the doc... O_o

english is not my mothertongue... but i´m learning.

i will try to use this in 3 steps for the whole sketch... !bright !mid !dark...

the fine-tuning for the effects that cause the Wemos to crash (no jumping balls anymore)

Set all effects to a certain duration 20-30 sec. (timer, counter & repeats)

Brightness by command? the default doesn't seem to work... "#define BRIGHTNESS 100"

Is it possible to adjust the Rainbow Glitter (from Neopixel) for this? (i found it ♥)

• Is it possible to additionally set a VU meter as a selectable effect?

Now i call 4 times the "Brightness" in this sketch...

Begin

#define LED_TYPE WS2811
#define BRIGHTNESS 100 // a little dim for recording purposes
#define COLOR_ORDER GRB

Message declaration

String BrightMessage = "!bright";
String MidMessage = "!mid";
String DarkMessage = "!dark";

in Setup

FastLED.addLeds<WS2811, PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
FastLED.setBrightness( BRIGHTNESS );

and at the END of the sketch

else if(ircMessage.text == BrightMessage)
{
FastLED.setBrightness(200); // 255 = max brightness, 0 = off
}
else if(ircMessage.text == MidMessage)
{
FastLED.setBrightness(100); // 255 = max brightness, 0 = off
}
else if(ircMessage.text == DarkMessage)
{
FastLED.setBrightness(40); // 255 = max brightness, 0 = off
}
return;
}

}

is this correct?

is there a better way?

 

it seems to work... call effect (normal) -> lights off -> brightness -> call effect = changed

If it works ... 😁 
Like I said: you may need to add a leds.show(); -- not sure if it is needed.

Something like this to make it visible right away.

...
else if(ircMessage.text == DarkMessage)
{
  FastLED.setBrightness(40); // 255 = max brightness, 0 = off
  leds.show();
}

Haha ^^ if i use the "leds.show();" after "FastLED.setBrightness(xxx);"  it shows me errors... without is all right. :D

------------------------------------------------------------------------

Whoo! I discovered something, tried it for hours and still can't get it right.

I need help rebuilding / rewriting if possible...

String AchtungMessage = "Achtung!";
String WelcomeMessage = "VoHiYo";
String FollowMessage = "follow";
String SubMessage = "sub";
String BitsMessage = "bits";

/*
and the action
*/

else if(ircMessage.text == AchtungMessage)
  {
  Strobe(0xff, 0xff, 0, 10, 50, 1000);
  }

to

// startsWith() checks to see if a String starts with a particular substring:
String stringOne = "Achtung!";
Serial.println(stringOne);
if (stringOne.startsWith("Achtung!")) { // effect start }
String stringTwo = "VoHiYo";
Serial.println(stringTwo);
if (stringTwo.startsWith("VoHiYo")) { // other effect start }

and for follow, sub & bits

// Set up a String:
String stringThree = "Thank you for your follow...";
Serial.println(stringThree);

// substring(index) looks for the substring from the index position to the end:
if (stringThree.substring(19) == "follow") {// other effect start }

I despair because in my sketch so many functions are distributed from LOOP to CALLBACK and CLIENT.LOOP ...

If it works to recognize individual phrases from a whole text, I can unplug my old Arduino Nano from the USB and have one less program running when streaming, which consumes resources.

BUT PLEASE NOT IMMEDIATELY!   🤣 🤣 🤣

I won't get to anything else this weekend 🤣 🤣 🤣

So far it has been so funny, as soon as I unplugged the cable and closed the Arduino IDE, I was either allowed to read the next comment, or I found errors during the test run, which doesn't give me peace of mind. ^^

To-do list Brightness also done ✔
