In this activity, we will learn how to fade in and out the screen to create a glowing animation. Let's get started!

|
Let's start by adding the code to display an image. Use `basic->plot image` to draw your favorite image.
|
|
|
|
```
|
|
basic.plotImage(`
|
|
. . . . #
|
|
# . . # .
|
|
. # # . .
|
|
. # # . .
|
|
# . . # .
|
|
`) // ***
|
|
```
|
|
|
|
We can control the brightness of the LED screen with code. That's just what we need to create a **glowing** animation: first we **fade out**, then **fade in**. Add a new line of code to **fade out** the screen.
|
|
|
|
```
|
|
basic.plotImage(`
|
|
. . . . #
|
|
# . . # .
|
|
. # # . .
|
|
. # # . .
|
|
# . . # .
|
|
`)
|
|
led.fadeOut(700) // ***
|
|
```
|
|
|
|
Run your script to make sure it works as expected then add another line of code to **fade in** the screen.
|
|
|
|
```
|
|
led.fadeIn(700)
|
|
```
|
|
|
|
Finally, add a `basic->forever` loop and move the fade out and fade in code into the forever to repeat the glow pattern.
|
|
|
|
```
|
|
basic.plotImage(`
|
|
. . . . #
|
|
# . . # .
|
|
. # # . .
|
|
. # # . .
|
|
# . . # .
|
|
`)
|
|
led.fadeOut(700) // ***
|
|
led.fadeIn(700) // ***
|
|
```
