# Fade in
|
|
|
|
Gradually increase the [LED screen](/device/screen) brightness until the LED lights are at full brightness.
|
|
|
|
```sig
|
|
led.fadeIn(700);
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* ms - [Number](/reference/types/number); the speed by which the screen brightness is increased, expressed in milliseconds (1,000 milliseconds = 1 second). The smaller the number the faster the screen brightness increased.
|
|
|
|
### Example: fading dot
|
|
|
|
The following code turns on centre LED and then gradually increases and decreases the screen brightness (the centre LED pulses 5 times):
|
|
|
|
```blocks
|
|
led.plot(2, 2)
|
|
for (let i = 0; i < 5; i++) {
|
|
led.setBrightness(0)
|
|
led.fadeIn(100)
|
|
basic.pause(100)
|
|
led.fadeOut(100)
|
|
}
|
|
```
|
|
