Function for converting milliseconds to minutes? I'm playing around with a Neopixel strip and want to be able to enter the amount of minutes I want an LED to do something rather than in milli seconds. So for example, 

void loop() {

colorWipe(strip.Color(0, 0, 255), 50);
delay(sConversion(5));

colorWipe(strip.Color(0, 0, 0), 50);
delay(sConversion(5));


In my mind this should then delay the code by 5 minutes instead of doing

void loop() {
colorWipe(strip.Color(0, 0, 255), 50);

delay(300000);


The function I wrote is

sConversion(int minutes) {
    int milli = minutes * 60000;

    return milli
};


When I write this same function in JS it returns the correct value, 300000. But when I run it in the Arduino IDE the blue light never changes.

I have this function outside my void loop() and void setup(). Is that the correct place to put it? I have no errors returned.

Full code sample

void setup() {


strip.begin();
strip.show(); 

}

int sConversion(int minutes) {
    int milli = minutes * 60000;

return milli;
}

void loop() {


colorWipe(strip.Color(0, 0, 255), 50); // Blue
delay(sConversion(1));



colorWipe(strip.Color(102, 204, 0), 50); // Green
delay(300000);
}

void colorWipe(uint32_t c, uint8_t wait) {
for (uint16_t i = 0; i &lt; strip.numPixels(); i++) {
    strip.setPixelColor(i, c);
    strip.show();
    delay(wait);
    };
};


Is this the reason? 


  No other reading of sensors, mathematical calculations, or pin manipulation can go on during the delay function, so in effect, it brings most other activity to a halt.

Your sConversion returns an int as argument. You need to declare it as unsigned long. 

This is what you are lookin for:

unsigned long conv(int x) {
  return x * 600000L;
}
