Neo Pixel Strip

CODE

// 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’
}

void loop() {
// Some example procedures showing how to display to the pixels:

colorWipe(strip.Color(59, 60, 7), 50); // Green
colorWipe(strip.Color(0, 0, 500), 50); // Blue

colorWipe(strip.Color(0, 255, 255), 0); // Red
colorWipe(strip.Color(0, 0, 0, 0), 50); // White

}

// Fill the dots one after the other with a color
void colorWipe(uint32_t c, uint8_t wait) {
for(uint16_t i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, c);
strip.show();
delay(wait);
}
}

void pulseWhite(uint8_t wait) {
for(int j = 0; j < 256 ; j++){
for(uint16_t i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, strip.Color(0,0,0, j ) );
}
delay(wait);
strip.show();
