交流调光器代码灯泡在闪烁前不亮

Question

我的代码有问题...我正在使用带有Arduino的交流调光器模块，我想让灯光发光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，灯不亮 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及其下面的代码。 它发光

我真的很陌生，请帮助我

您观察到的 5 秒延迟是 Arduino 的启动时间。Arduinos 引导加载程序将等待新的固件，因为您的草图被执行。

如果要将灯打开 5 秒钟，请将delay(200);替换为delay(5000);。
