Hallo Comunity, ich habe das Problem, dass mein Code, der eigentlich gehen sollte nicht Funktioniert. Das problem hängt irgendwie mit if Abfragen und der SD Karte zusammen
Dieser Code funktioniert:
// Glediator Arduino UNO sketch by Jens Andrée
// 500k bauds with 80 pixels no problem
// sdcard stream for stand-alone operation.
#include <SoftwareSerial.h>
#include <FastLED.h>
#include <SPI.h>
#include <SD.h>

#define DATA_PIN 3
#define CMD_NEW_DATA 1

{

}

wenn ich aber die Kommentare unten entferne sodass der Code aktiv ist, funktioniert am anfang das Boot.dat, aber wenn ich über Bluetooth dateien starte funktioniert das nicht.
