Neopixel

Hallo, kann mir jemand helfen?
Ich möchte meine Neopixels mithilfe einem Knopf durch verschiedene Modis durchschalten können.
Ich kann aber den Modus nicht umschalten…

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
  #include <avr/power.h>
#endif
//const int Button = 5;
int mode         = 1;
int ButtonState = 3;
#define NUM_PIXELS 12
#define PIN 2
int Button = 5;

// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
//   NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
//   NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
//   NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
//   NEO_RGBW    Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(12, PIN, NEO_GRB + NEO_KHZ800);

// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel.  Avoid connecting
// on a live circuit...if you must, connect GND first.

Wie hast Du denn Deinen Button angeschlossen? PullUp- oder PullDown-Widerstand dran?

Gruß Tommy

noiasca:
wie hast du dir vorgestellt, dass du hier rauskommst?

 while (mode==1){

theaterChase(strip.Color(127, 127, 127), 50);

}

Hat der Arduino keinen Notausgang?
Uwe

Doch, wenn Du den Wachhund aktivierst. Der dürfte hier aber auch nicht sinnvoll sein.

Hallo,

ich denke Du hast es zunächst mit while versucht und dann auf if gewechselt , bei 2 u 3 ist es ja richtig bei 1 hast Du es vergessen zu ändern.
