Process

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.

    if (timeStarter == true){
        
        long timeNow = millis();

        int g = 255;
