### 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)

|
||||
* 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.
