How can I change an "if" in an arduino code ?
So I have this code from James Hutton and what I want to do is to change the "rainbowCycle" to something else, like "NeoPixel_Cylon_Scrolling_Eye". Is it possible ? Thank you very much !

You just copy code you do not know what it is doing.
When I get into such a situation I will make a flow chart out of each statement like that do while loop for the whole code until I see what function it performs.

Hi, thank you.
I did manage to work it out, now when there is no music, the cylon effect kicks in, the problem i have now, is that it wont go back to the original code, when it gets music.
Can you please have a look?
Thank you
The modified code:
================
#include <Adafruit_NeoPixel.h>
#define PIN 6
#define lightCount 286
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream
// NEO_HZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip)

So first of all thank you for the explanation, i do appreciate your long answer!
But i don't really have time to learn the this coding... so what I need is someone who can make this happen, or can give me examples.
Thank you!
Answer 2 years ago
Ah...yes, I see. You don't have time and inclination to learn and you want someone else to do the work for you. well, ok. good luck.

Yes. Its possible. What happens when you try it ?

So, I don't even know where to insert the code...

}
}while (vol == 0);

}

}
strip.show();
}

}
}
}
