Hallo zusammen
Ich benötige Hilfe im Zusammenhang mit einer Lichtshow und Buzzer Musik gleichzeitig.
Ist das überhaupt möglich?
Ausgangslage:
Ich möchte für meine Schwester einen Pullover mit licht (neopixel) und Musik Weihnachtsmusik machen.
beides voneinander getrennt funktioniert einwandfrei. Auch das zusammenführen ging ohne Probleme,
bis auf das Problem, dass Musik und licht voneinander getrennt laufen.
Ich stehe also voll auf dem Schlauch...
Ich bitte um eure HILFE.
Vielen Dank
Patrick
Anbei der Code:
#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h>
#endif
#define PIN 6
// 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(10, PIN, NEO_GRB + NEO_KHZ800);
