Neopixel条带动画切换问题

Question

我在床上放了一条Neopixels，用来做暗光。最近，我决定添加一个声音传感器，这样我就可以鼓掌一次来切换我正在使用的灯光动画。现在我遇到了让我的代码正常工作的问题。我可以把灯打开，但我不能再拍手把它们关掉。我怀疑的问题可能是，我只给出了在用于运行灯光动画的while循环结束时关闭灯光动画的条件，然而，我不知道我可以做些什么来解决这个问题。有人能帮帮我吗？

#include <Adafruit_NeoPixel.h>
#ifdef __AVR__
#include <avr/power.h>
#endif
#define PIN 6

Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);
int soundSensor = 2;
int LED = 13;


void setup() 
{

// This is for Trinket 5V 16MHz, you can remove these three lines if you are not using a Trinket
  #if defined (__AVR_ATtiny85__)
    if (F_CPU == 16000000) clock_prescale_set(clock_div_1);
  #endif
  // End of trinket special code

  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
  pinMode (soundSensor, INPUT);
  pinMode (LED, OUTPUT);
}

void loop()
{
  int toggle = 0;
  int statusSensor = digitalRead (soundSensor);

  if (statusSensor == 1 && toggle == 0)
  {
    toggle= 1;
    digitalWrite(LED, HIGH);
    //statusSensor = 0;
    statusSensor = digitalRead (soundSensor);
  }

    //NEOPIXEL CODE:
  while (toggle == 1)
  {
  digitalWrite(LED, HIGH);
  delay(200);
  digitalWrite(LED, LOW);
  delay(200);
  digitalWrite(LED, HIGH);
  delay(200);
  digitalWrite(LED, LOW);
  digitalWrite(LED,HIGH);
  colorWipe(strip.Color(255, 0, 0), 50);     // Red
  colorWipe(strip.Color(0, 255, 0), 50);     // Green
  colorWipe(strip.Color(255,255,255), 50);   //White
  colorWipe(strip.Color(255,255,255), 50);
  colorWipe(strip.Color(0, 0, 255), 50); // Blue
  rainbow(20);
  rainbowCycle(20);
  if(statusSensor == 1){
    toggle = 0;
  }
  }

  if (statusSensor == 1 && toggle == 1)
  {
    toggle = 0;
    digitalWrite(LED, LOW);
  }


}


//NEOPIXEL Functions:
void colorWipe(uint32_t c, uint8_t wait) {
  for(uint16_t i=0; i<strip.numPixels(); i++) {
    strip.setPixelColor(i, c);
    strip.show();
    delay(wait);
  }
}

void rainbow(uint8_t wait) {
  uint16_t i, j;

  for(j=0; j<256; j++) {
    for(i=0; i<strip.numPixels(); i++) {
      strip.setPixelColor(i, Wheel((i+j) & 255));
    }
    strip.show();
    delay(wait);
  }
}

// Slightly different, this makes the rainbow equally distributed throughout
void rainbowCycle(uint8_t wait) {
  uint16_t i, j;

  for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel
    for(i=0; i< strip.numPixels(); i++) {
      strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255));
    }
    strip.show();
    delay(wait);
  }
}

uint32_t Wheel(byte WheelPos) {
  WheelPos = 255 - WheelPos;
  if(WheelPos < 85) {
    return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);
  }
  if(WheelPos < 170) {
    WheelPos -= 85;
    return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);
  }
  WheelPos -= 170;
  return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0);

将切换设置为0时，不会向新像素条带写入任何颜色。所以它们将被留在它们所处的任何状态。您可以通过在将切换设置为零时将它们全部设置为“黑色”(即禁用)来修复此问题：

if(statusSensor == 1) {
    toggle = 0;
    for(uint16_t i=0; i<strip.numPixels(); i++) {
       strip.setPixelColor(strip.Color(0,0,0));
    }
    strip.show();
}

如果你只是想让它们立即出现，你不需要任何延迟，但也许你可以让它们淡出？
