glowing sword challenges

Coding challenges for the glowing sword tutorial. #docs

Before we get started

Complete the glowing sword 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.
