我正在使用 arduino 用红外遥控器制作云灯。我正在尝试使其中一个按钮模拟雷暴，其中白色 LED 将在特定代码下的布尔语句内随机闪烁...问题是，我只能让它经历一次闪光期...这是风暴的部分代码：

#include <IRremote.h>
// My modified code
int RECV_PIN = 11;
int red = 2;
int yellow = 3;
int green = 4;
int blue = 5;
int purple = 6;
int white = 7;
long randOn = random(10,200);
long guess = random(1000,20000);

#define powercode 16726725
#define stormcode 4294967295                   




IRrecv irrecv(RECV_PIN);
decode_results results;

void setup()

      pinMode(green, OUTPUT);
        pinMode(blue, OUTPUT);
          pinMode(purple, OUTPUT);
            pinMode(white, OUTPUT);
  irrecv.enableIRIn(); // Start the receiver

    irrecv.resume(); // Receive the next value

}

如果我继续添加这些延迟和数字写入，我无法将“通道”或 LED 更改为不同的颜色，我会卡住直到事情完成！感谢您提前帮助我！

您是正确的，使用延迟功能时不会发生其他操作。您应该尝试使您的代码类似于blinkWithoutDelay示例。所以你可以做这样的事情

// struct that represents the values for each led
struct LED{
  int pin; // pin # the led is connected to
  int state; // state of the led , on or off
  long interval; // how long we should wait before toggling
  long timeToggled; // last time we toggled
};

if(results.value == 16759365){
  digitalWrite(0,HIGH);
  digitalWrite(1,HIGH);
  digitalWrite(2,HIGH); 

  LED white = {0,HIGH,100,millis()}; 
  LED yellow = {1,HIGH,10,millis()};
  LED blue = {2,HIGH,420,millis()};

  results = readIr(); // check the ir value again and keep looping until it changes
  while(results.value == 16759365){
     toggleLed(white);
     toggleLed(yellow);
     toggleLed(blue);
     results = readIr(); // if ir value hasnt changed keep looping until it does
  }

  digitalWrite(0,LOW);
  digitalWrite(1,LOW);
  digitalWrite(2,LOW);
}



void toggleLed(struct LED currentLed){
  unsigned long currentMillis = millis();

  if(currentMillis - currentLed.timeToggled > currentLed.interval) {
    // save the last time you blinked the LED 
    currentLed.timeToggled = currentMillis;   

    // if the LED is off turn it on and vice-versa:
    if (currentLed.state == LOW)
      currentLed.state = HIGH;
    else
      currentLed.state = LOW;

    // set the LED with the ledState of the variable:
    digitalWrite(currentLed.pin, currentLed.state);
  }
}
