# glowing sword challenges
Coding challenges for the glowing sword tutorial. #docs
## Before we get started
2016-04-13 17:27:45 +02:00
Complete the [glowing sword](/lessons/glowing-sword/activity) activity and your code will look like this:
2016-03-26 00:47:20 +01:00
```
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
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.
