Question

我总共有一组LED 12：6个是蓝色，6个是红色。我有一些循环，有助于杂乱地以设定的间隔打开和关闭LED。但现在我想做到这一点，它有while循环控制LED的速度变化多长时间。到目前为止我已经做了两个并且它们都工作了但是第二个我把for循环放在它里面并没有做任何事情。

int redLEDPins[] = {2,3,4,5,6,7};
int blueLEDPins[] = {8,9,10,11,12,13};
int LED_Amount = 6;
int led_delay = 1000;

unsigned long time_since_last_reset = 0;
int wail = 5000;
int yelp = 3000;
int phaser = 3000;
int hilo = 3000;

void setup() {
  for (int i; i < LED_Amount; i++) {
    pinMode(redLEDPins[i], OUTPUT);
    pinMode(blueLEDPins[i], OUTPUT);
  }
  Serial.begin(9600);
}

void loop() {
  //wail while loop
  time_since_last_reset = millis();
  while((millis() - time_since_last_reset) < wail) {
    led_delay = 250;
    Serial.print("delay: ");
    Serial.println(led_delay);
    digitalWrite(2, HIGH);
    delay(500);
    digitalWrite(2, LOW);
    delay(500);
  }

  //yelp while loop
  time_since_last_reset = millis();
  while((millis() - time_since_last_reset) < wail){
    led_delay = 50;
    Serial.print("delay: ");
    Serial.println(led_delay);
    for (int i; i < LED_Amount; i++) {
      digitalWrite(redLEDPins[i], HIGH);
      digitalWrite(blueLEDPins[i], LOW);
      Serial.println("Red on ");
      Serial.println("Blue off");
    }
    delay(led_delay);
    for (int i; i < LED_Amount; i++){
    digitalWrite(redLEDPins[i], LOW);
    digitalWrite(blueLEDPins[i], HIGH);
    Serial.println("Red off ");
    Serial.println("Blue on");
    }
    delay(led_delay);
  }
}

theData= [[0, 1, 1, 1],[0, 1, 3, 1],[3, 4, 1, 3],[0, 1, 2, 0],[2, 1, 0, 0]]

可能是因为你没有初始化我？

Arduino：for循环不能在while循环中工作
