My third work is about flicker water clock. At the bottom of the water clock, It has a flicker light. The flicker time is different. So it will create a fake illusion that the water flows towards the opposite direction.

// pixels off the ends of the strip, we don’t need to watch for that.
strip.setPixelColor(pos – 2, 0x100000); // Dark red
strip.setPixelColor(pos – 1, 0x800000); // Medium red

I learned a lot through this activity. First, I know how to do a complete costume. During this process, I think my sew skill is improved. Besides, I think coding actually is not very difficult, especially some basic coding. If we know the resource of coding library, it will be very convenient to do it.

Black Wuchang is Chinese ghost. The reason why I want to choose it to as my Halloween costume is I want to spread Chinese culture, and let foreigners to know Chinese ghost.
My design’s hardest part is the structure of hat. So I plan to use wire to build frame. And then, use black fabric to cover it.
The key point is Led behind the paper. I plan to use coding to blink light. I will also fix LED on Iron chains. The Iron chain is the weapon of Black Wuchang.
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream, correct if colors are swapped upon testing
// NEO_RGBW Pixels are wired for RGBW bitstream
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stick
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRBW + NEO_KHZ800);
void setup() {
strip.setBrightness(BRIGHTNESS);
strip.begin();
strip.show(); // Initialize all pixels to ‘off’

colorWipe(strip.Color(0, 255, 255), 0); // Red

}
// Fill the dots one after the other with a color

This product is for children whose parents can’t be with them. If they miss their parents, they can light the lamp on this pillow. The parents can receive the message through the APP. This allows parents to feel their children’s emotions in real time.
