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) // ***
