AC 调光器 Code 灯泡在闪烁前不发光

Question

我的代码有问题...我正在使用带有 arduino 的交流调光器模块，我想让灯发光 5 秒然后闪烁两次然后重复

int AC_LOAD = 3;    // Output to Opto Triac pin
int dimming = 128;  // Dimming level (0-128)  0 = ON, 128 = OFF

void setup()
{
  pinMode(AC_LOAD, OUTPUT);// Set AC Load pin as output
  attachInterrupt(0, zero_crosss_int, RISING);  // Choose the zero cross interrupt # from the table above
}

//the interrupt function must take no parameters and return nothing
void zero_crosss_int()  //function to be fired at the zero crossing to dim the light
{
  // Firing angle calculation : 1 full 50Hz wave =1/50=20ms 
  // Every zerocrossing thus: (50Hz)-> 10ms (1/2 Cycle) 
  // For 60Hz => 8.33ms (10.000/120)
  // 10ms=10000us
  // (10000us - 10us) / 128 = 75 (Approx) For 60Hz =>65

  int dimtime = (75*dimming);    // For 60Hz =>65    
  delayMicroseconds(dimtime);    // Wait till firing the TRIAC    
  digitalWrite(AC_LOAD, HIGH);   // Fire the TRIAC
  delayMicroseconds(10);         // triac On propogation delay 
         // (for 60Hz use 8.33) Some Triacs need a longer period
  digitalWrite(AC_LOAD, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC
}

void loop() 


{
 {
   int e = 5;
   dimming = e;
   delay(200);
 }
  {
  for (int i=128; i >= 5; i--){
  dimming=i;
  delay(2);
  }

  for (int j=5; j <= 128; j++){
  dimming=j;           
  delay(2); // this value is the light delay timing 
  }
  //delay(3);  // this value is the gap timing 


  for (int i=128; i >= 5; i--){
  dimming=i;
  delay(2);
  }

  for (int j=5; j <= 128; j++){
  dimming=j;           
  delay(2); // this value is the light delay timing 
  }
  //delay(3);  // this value is the gap timing 
  }}

当我使用此代码时，灯不会亮起 5 秒然后闪烁。它有 5 秒的延迟然后闪烁

{
   int e = 5;
   dimming = e;
   delay(200);
 }

但是如果我只使用这部分代码和下面的代码。它发光

我真的是编程新手，请帮助我

您观察到的 5 秒延迟是 Arduino 的启动时间。 Arduinos 引导加载程序将在执行您的草图之前等待新固件。

如果您想让灯亮 5 秒，请将 delay(200); 替换为 delay(5000);。
