i am trying to make an alarm clock with esp8266 and ws2812b leds. On alarm time it must call the sunrise() function. The sunrise() function works fine when i put it directly in the loop function. But it doesn't work in alarm trigger.
if (AlarmData.AlarmOn[Current.Day])
{
if (!AlarmActive)//do not enter this routine if alarm already active
{
if (Current.Hour == AlarmData.Hour[Current.Day])
{
if (Current.Minute == AlarmData.Minute[Current.Day])
{
if (Current.Second > 0 && Current.Second < 3)
{
AlarmActive = true;
sunrise();
alarmTriggerTime = micros();
Serial.println("Its time for your alarm!");
}
}
}
}
}
My code is below. thanks in advance for your help

Your sunrise function should be called over and over, every call changes the LED color a slight bit. This is why it works then you put it into the loop function.
However, you have guarded it so that it is specifically only called once - so now it is called, sets the LEDs to the dimmest setting possible, and is not called again.
What you need to do is separate this out into two parts: One that detects when to activate sunrise, and one that is continuously called when it is time. F.ex:
void loop()
{
/* stuff */
if (AlarmData.AlarmOn[Current.Day])
{
if (!AlarmActive) // do not enter this routine if alarm already active
{
if (Current.Hour == AlarmData.Hour[Current.Day])
{
if (Current.Minute == AlarmData.Minute[Current.Day])
{
if (Current.Second > 0 && Current.Second < 3)
{
AlarmActive = true;
alarmTriggerTime = micros();
Serial.println("Its time for your alarm!");
}
}
}
}
}
if (AlarmActive)
sunrise();
}
