}

Usage

Easy (global brightness, sending an array of colors)

Blinkt blinkt = new Blinkt();
blinkt.setBrightness(1);
blinkt.write(new int[]{Color.RED, Color.GREEN, Color.BLUE, Color.DKGRAY, Color.YELLOW, Color.MAGENTA, Color.CYAN, 0xFF9B6E26});
blinkt.close();

Advanced (brightness per LED, sending colors individually, showing in a reversed order)

Blinkt blinkt = new Blinkt(DATA_GPIO, CLOCK_GPIO);
blinkt.setDirection(Blinkt.Direction.REVERSED);

for (int i = 0; i < Blinkt.LEDSTRIP_LENGTH; i++) {
    int color = Color.HSVToColor(255, new float[]{i * 360.f / Blinkt.LEDSTRIP_LENGTH, 1.0f, 1.0f});
    int brightness = (int) ((float) Blinkt.MAX_BRIGHTNESS / Blinkt.LEDSTRIP_LENGTH * (i + 1));
    blinkt.setColor(i, color, brightness);
}
blinkt.show();

blinkt.close();
