### Example: change brightness
This program makes the screen brightness 100% (255). Then it turns on
the center LED (`2, 2`), waits for one second and then sets the screen
brightness to 50% (128):
```blocks
led.setBrightness(255)
led.plot(2, 2)
basic.pause(1000)
led.setBrightness(led.brightness() / 2)
```

### Parameters ### Parameters
* value : [Number](/reference/types/number) - the brightness of the LED screen expressed as a number between 0 and 255 * a [number](/reference/types/number) that means how bright the screen is when it is turned on, from `0` (darkest) to `255` (brightest). For example, the number `127` means the screen is halfway bright when it is turned on.
