WS2812

Full color LED driver.
Not only one LED. Capable of chaining leds.

WS2812 is embed in various Full Color LEDs.

wire({din, [vcc, gnd]})

connect VDD and GND to obniz Board and drive it.
And, wire DIN(Data in) to obniz Board. and write a code below

// Javascript Example
var leds = obniz.wired("WS2812", {gnd:0, vcc: 1, din: 2});
leds.rgbs([
  [0xFF, 0x00, 0x00], // red
  [0x00, 0x00, 0xFF]  // blue
])

vcc and gnd is optional

// Javascript Example
var led = obniz.wired("WS2812", {din: 2});

rgb(red, green, blue)

change color.
When you chaining LED, this will change only top of leds.

// Javascript Example
var led = obniz.wired("WS2812", {gnd:0, vcc: 1, din: 2});
led.rgb(0xFF, 255, 0); // Yellow

hsv(hue, saturation, value)

change color from hsv values.
When you chaining LED, this will change only top of leds.

hue : 0 ~ 360
saturation : 0 ~ 1
value : 0 ~ 1

// Javascript Example
var led = obniz.wired("WS2812", {gnd:0, vcc: 1, din: 2});
led.hsv(180, 0.5, 1);

rgbs([[r,g,b],,,,])

change colors.
You can specify colors of chained leds.
max chain length is 85(It depends on SPI max length)

// Javascript Example
var led = obniz.wired("WS2812", {gnd:0, vcc: 1, din: 2});
led.rgbs([
  [0xFF, 0x00, 0x00], // red
  [0x00, 0x00, 0xFF]  // blue
])

hsvs([[r,g,b],,,,])

change colors.
You can specify colors of chained leds.
max chain length is 85(It depends on SPI max length)

// Javascript Example
var led = obniz.wired("WS2812", {gnd:0, vcc: 1, din: 2});
led.hsvs([
  [180, 0.5, 1],
  [0, 1, 1]
])
