Outcome
- Ambient orb: The Neopixel will be triggered and light up in white 15 minutes before the event on Google Calendar starts. It will gradually turn red and blink when there is only 1 minute left. Video

I was trying to make the Neopixel off once the countdown for the event completes. In order to do that, I set else if ( ((durationOfFade - timeElapsed) > 0) && ((durationOfFade - timeElapsed) < 1000*10)) to indicate when to blink and when to stop from blinking so I can turn the Neopixel off by adding the next line of code. Yet, the code didn't function well and I couldn't stop it from blinking.
void loop() {
if (timeStarter == true){
long timeNow = millis();
long timeElapsed = timeNow - timeStartedAt;
int r = 255;
int g = 255;
int b = 255;
if (timeElapsed < durationOfFade){
int colorValue = map(timeElapsed, 0, durationOfFade, 0, 255);
for (int i = 0; i < strip.numPixels(); i++){
strip.setPixelColor (i, r, g - colorValue, b - colorValue);
}
strip.show();
delay (10);
}else if ( ((durationOfFade - timeElapsed) > 0) && ((durationOfFade - timeElapsed) < 1000*10)){
for (int i = 0; i < strip.numPixels(); i++){
strip.setPixelColor (i, 255, 0, 0);
}
strip.show();
delay (100);
for (int i = 0; i < strip.numPixels(); i++){
strip.setPixelColor (i, 0, 0, 0);
}
strip.show();
delay (100);
} else {
for (int i = 0; i < strip.numPixels(); i++){
strip.setPixelColor (i, 0, 0, 0);
}
strip.show();
delay (100);
}
Serial.println ((durationOfFade - timeElapsed));
delay(1000);
}
