+Rotate images with a while loop. 
+
+### ~avatar avatar
+
+Welcome! This tutorial will teach how to rotate images with a **while loop**. Let's get started!
+
+### ~
+
+Let's start by creating a global variable called `rotating` and initialize it to true. This well indicate when the animation should be displaying.
+
+```blocks
+let rotating = true;
+```
+
+Now we need a while loop that will be executed only if the variable rotating is true.
+
+```blocks
+let rotating = true;
+while (rotating) {
+    basic.pause(20)
+    
+}
+```
+
+Let's create and show an animation of a diagonal line that rotates clockwise. We need a pause so that the battery does not burn out.
+
+```blocks
+let rotating = true;
+while (rotating) {
+    basic.pause(20)
+    basic.showLeds(`
+        # . . . .
+        . # . . .
+        . . # . .
+        . . . # .
+        . . . . #
+        `)
+    basic.showLeds(`
+        . . # . .
+        . . # . .
+        . . # . .
+        . . # . .
+        . . # . .
+        `)
+    basic.showLeds(`
+        . . . . #
+        . . . # .
+        . . # . .
+        . # . . .
+        # . . . .
+        `)
+    basic.showLeds(`
+        . . . . .
+        . . . . .
+        # # # # #
+        . . . . .
+        . . . . .
+        `)
+}
+```
