In the previous section, we just created a display that instantly swaps all pixel colors on any CheerLights update.

NeoPixels are individually addressable LEDs, which means you can create a lot more interesting display with your CheerLights. Let's try to create a displays that slowly updates all your pixels gradually as the color changes in a fluid motion. To do this, update the code in your setNeoPixelsColor() function to the following:

    void setNeoPixelsColor() {
        for (uint16_t i = 0; i < strip.numPixels(); i++) {
            delay(100);
            strip.setPixelColor(i, cheerLightsRed, cheerLightsGreen, cheerLightsBlue);
            strip.show();
        }
    }

This will create a flowing motion update of color every time there is a color change.

You may try other interesting combinations of displays. As an exercise, try to make a shimmering effect if the color is not updated in a while.
