## Before we get started
|

|
|
|
Complete the [glowing sword](/lessons/glowing-sword/activity) activity and your code will look like this:

|
|
|
|
|
|
|
|
```
|
|
|
|
|
basic.plotImage(`
|
|
|
|

. . . . #

|
|

# . . # .

# . . # .
|
|
|
|
|
`)
|
|
|
|
|
led.fadeOut(700)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Challenge 1
|
|
|
|
|
|
|
|
|
|
Now, let's add `basic->pause(1000)` after the fade in so that there will be a 1000 millisecond (1 second) delay after the fade out.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
basic.plotImage(`
|
|
|
|
|
. . . . #
|
|
|
|
|
# . . # .
|
|
|
|
|
. # # . .
|
|
|
|
|
. # # . .
|
|
|
|
|
# . . # .
|
|
|
|
|
`)
|
|
|
|
|
led.fadeOut(700)
|
|
|
|
|
basic.pause(1000) // ***
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
* `run main` the code to see if it works as expected.
|
|
|
|
|
|
|
|
|
|
### Challenge 2
|
|
|
|
|
|
|
|
|
|
### @video td/videos/glowing-sword-2
|
|
|
|
|
|
|
|
|
|
After the pause, let's add `led->fade in(2000)` so that we can create a glowing effect.
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
basic.plotImage(`
|
|
|
|
|
. . . . #
|
|
|
|
|
# . . # .
|
|
|
|
|
. # # . .
|
|
|
|
|
. # # . .
|
|
|
|
|
# . . # .
|
|
|
|
|
`)
|
|
|
|
|
led.fadeOut(700)
|
|
|
|
|
basic.pause(1000)
|
|
|
|
|
led.fadeIn(2000) // ***
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
* `run main` 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 sword can fade out again.
|
|
