The sources of Trollo_meo's LED matrix project and some context;

I’m having a problem with my project I’ve made with your projects…

I would like to do an LED-matrix with WS2812b LED-stripes.

So I picked 6 different project’s from this website and I put them into my sketch.

Now I’m having a problem…

I wanted to work with an HIGH respective LOW pegel.

Everything is good and at the right pin I’m having HIGH if I close the switch.

But the program doesn’t start my function where the LED’s will start to work…

I’m sorry for my bad english I’m native german speaker…

It’s a pretty big project sorry.

Even though this is an English forum; if you really get stuck with the English language, throwing in a few German expressions is OK.
I do speak German as well but would like to keep the forum posts as readable as possible for other users. 

I'm not 100% clear of the issue you're running into, but I did notice something in your loop() that will cause issues;

void loop() {
  //1. aufblinken 
  if (aufblinkeninput == HIGH) {
    TwinkleRandom(); //if the pin aufblinkeninput is HIGH the function TwinkleRandom starts
  } ...
}

I see you want to test if a button state is HIGH or not.
You properly define the button on that pin as such in setup().

However, ... you never read the actual button state. In your code you read the value of the variable (holding the pin number) instead.

So in setup() you set a particular Arduino pin to be an input for a button:

pinMode(aufblinkeninput, INPUT);

But in the loop you're testing this fixed number (aufblinkeninput) to be HIGH or not.
However, this would be the pin number for that button (int aufblinkeninput = 12; ), and not the actual value of what is going on on that pin.
The state of the button is not being read either. You'll need to use the "digitalRead()" function for that.

A short recap for that particular example (you'll need to apply this to the other variables as well)

This is what you had:

int aufblinkeninput = 12;
...
void setup() {
  ...
  
  pinMode(aufblinkeninput, INPUT);
  ...
}
void loop() {
  ...
  
 if( aufblinkeninput == HIGH) {                                                           
   TwinkleRandom();
 }
 
 ...
}

Now change that to this (eg. you will need to apply this to the other buttons as well;

#define aufblinkeninput 12  // define the pin for this button
...
void setup() {
  ...
  
  pinMode(aufblinkeninput, INPUT); 
  ...
}
void loop() {
  ...
  
  if (digitalRead (aufblinkeninput) == HIGH) {
    TwinkleRandom(); 
  }
  ...
}

(I made the changes bold)

Hope this helps you get further with your project

So if u r having problems with my project I'll try to explain what I wanted to do...

So my idea is that I'm having a wooden board with an WS2812b LED-stripe mounted on it.

This stripe will show up in different modes.

(I've used Random color Twinkle ->aufblinken and Rainbow Cycle ->rainbowfade)

So now I'm having the programmed modes and I want to have 6 different switches where I can switch between those modes.

I've started with a switch case but it didn't work....

So I picked some if else.

Now I'm having the problem that if I have a logical 1 at the pin 12 for example (for aufblinken in this case) there's no output at my pin 6 wich is connected to the LED-stripe.

I'm sure that my mistake is in the programm cause everything works well in the montage to my arduino nano...

Myb that's the problem.

I havn't used other Arduinos except the Nano until yet.

Myb this helps u to understand what I'm struggeling with.

Now I've took the advices u gave me and switched everything in the programm...

But I'm having an error message:

Arduino: 1.8.5 (Windows 10), Board: "Arduino Nano, ATmega328P"

                     ^

(this error message is quiet common for me I'm having it every time I compile a programm even if it's working)

Error compiling for board Arduino Nano.

This report would have more information with

Can u help me with that error message?

The message:

# pragma message “FastLED version 3.003.001”

is actually not an error message (yes, I agree - why show it when it can confuse the user?) - so you can ignore that one.
It's just there so you can see which library version you're using.

The message:

ld returned 1 exit status

is a linker error - for some reason linking (ld) failed.
Maybe verbose output (File -> Preferences -> check "Show verbose output during: [ ] compilation".
Not sure if it will help.

Often this is related to the Arduino IDE - so also make sure you have the latest version of the Arduino IDE (which includes "ld").

As for the pins used: some pins can conflict.
I'm not an expert on this, but I know some pins are so called PWM pins (like PIN 6 and PINs 3, 5, 6, and 11) - see attached pictures (which can be quite confusing).
So my advice, since I'm not an expert either: start your project with 1 button. If it works OK, add another button. Keep doing this until you see it fail. For the last PIN added select another pin.

Another approach could be using the effect that you've tied to PIN 12 on a PIn you know that works. Just to make sure the effect does work.

Nevermind

I had to do some changes in my code from my aufblinken function.

It's working now

thank u sooooo much for your help and the projects u did

I really like the website and how u interact with people who want to do sth with the LED stripe

Respect really

U did and still do an awesome job with supporting people when they have problems

here's my code:

the only thing u might have to change is an option to end the function cause now it's staying in the function if u selected it once.

But I'm sure that I and other people who want's to do sth similar will be able to programm that by themself.

that sounds pretty obvious...

thank u for telling me

as mostly fixing a problem cause new problems

I'm using an Arduino Nano...

I tried to compile the programm but I'm having a error message....

(I've addet the error message)
