[This guided tutorial](https://test.microbit.co.uk/td/lessons/glowing-mountain/tutorial) will teach you how to create a mountain that fades out.
|
||
|
|
|
||
|
|
```
|
||
|
|
images.createImage(`
|
||
|
|
. . . . #

|
||
|
|
`).showImage(0)
|
||
|
|
led.fadeOut(700)
|
||
|
|
```
|
||
|
|
|
||
|
|

|
|
||
|
|
Now, let's add `basic->pause(1000)` after the fade in so that there will be a 1000 millisecond delay after the fade out.
|
||
|
|
|
||
|
|
```
|
||
|
|
images.createImage(`
|

|
||
|
|
`).showImage(0)
|
||
|
|
led.fadeOut(700)
|
||
|
|
basic.pause(1000) // ***
|
||
|
|
```
|
||
|
|
|
||
|
|
* Run the code to see if it works as expected.

|
|
|
||
|
|
After the pause, let's add `led->fade in(2000)` so that we can create a glowing effect.
|
||
|
|
|
||
|
|
```
|
||
|
|
images.createImage(`
|
||
|

. # # . .
|
||
|
|
# . # # .
|
||
|
|
`).showImage(0)
|
||
|
|
led.fadeOut(700)
|
||
|
|
basic.pause(1000)
|
||
|
|
led.fadeIn(2000) // ***
|
||
|
|
```
|
||
|
|
|
||
|
|
* Run the code to see if it works as expected.
|
||
|
|
|
||
|
|
**Challenge 3**
|
||
|
|
|
||
|
|
Now add another `basic->pause(1000)` and `led->fade out(900)` so that the mountain can fade out again.
