## Install

```

## API

### Set A Single Pixel

The bread and butter of Blintk! is setting pixels. You can set any of the 8 pixels on your Blinkt! to one of around 16
million colors!

The `brightness` argument is completely optional. Omit it to keep the last brightness value set for that particular
pixel.

``` javascript
blinkt.setPixel(index, red, green, blue, brightness)
```

| Parameter | Description | Required |
| ---------- | ------------------------------------------------------------------ | -------- |
| index | The horizontal position of the pixel (between 0 and 7 - inclusive) | Yes |
| red | The amount of red to be set (between 0 and 255 - inclusive) | Yes |
| green | The amount of green to be set (between 0 and 255 - inclusive) | Yes |
| blue | The amount of blue to be set (between 0 and 255 - inclusive) | Yes |
| brightness | The brightness to be set (between 0 and 1 - inclusive) | No |

### Set All Pixels

Sometimes you need to set all the pixels to the same color. This convenience method does just that!

The `brightness` argument is completely optional. Omit it to keep the last brightness values set for each pixel.

``` javascript
blinkt.setPixels(red, green, blue, brightness)
```

| Parameter | Description | Required |
| ---------- | ------------------------------------------------------------- | -------- |
| red | The amount of red to be set (between 0 and 255 - inclusive) | Yes |
| green | The amount of green to be set (between 0 and 255 - inclusive) | Yes |
| blue | The amount of blue to be set (between 0 and 255 - inclusive) | Yes |
| brightness | The brightness to be set (between 0 and 1 - inclusive) | No |

### Show

None of your pixels will appear on Blinkt! until you `show()` them. This method writes all the pixel data out to your
device.

``` javascript
blinkt.show()
```

### Clear

Exactly the same as calling `setAll(0,0,0)`, clear sets all the pixels to black.

You must also call `show()` if you want to turn Blinkt! off.

``` javascript
blinkt.clear()
```

### Enable/Disable Clear On Exit

Sometimes you want a script that runs and quits, leaving a pattern up on Blinkt!

``` javascript
blinkt.setClearOnExit(value)
```

| Parameter | Description | Required |
| --------- | ------------------------------------------------- | -------- |
| value | `true` to clear pixels on exit; otherwise `false` | No |

### Get A Single Pixel

Returns the colors and brightness for a particular pixel.

``` javascript
blinkt.getPixel(index)
```

| Parameter | Description | Required |
| --------- | ------------------------------------------------------------------ | -------- |
| index | The horizontal position of the pixel (between 0 and 7 - inclusive) | Yes |

### Constants

Blinkt! has 8 pixels. Simple. Use the constant `NUM_PIXELS` when you’re iterating over pixels, so you can avoid a *magic
number* in your code.

``` javascript
blinkt.NUM_PIXELS
```
