+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) // ***
+```
