 A variable is created for the number returned by the [brightness](/reference/led/brightness) function.
 
+```blocks
+let b = led.brightness();
+```

 ### Using variables
 
 Once you've defined a variable, just use the variable's name whenever you need what's stored in the variable. For example, the following code shows the value stored in `counter` on the LED screen:
 
-![](/static/mb/blocks/var-6.png)
+```blocks
+let counter = 1;
+basic.showNumber(counter);
+```
 
 To change the contents of a variable use the assignment operator. The following code sets `counter` to 1 and then increments `counter` by 10:
 
-![](/static/mb/blocks/var-7.png)
+```blocks 
+let counter = 1;
+counter = counter + 10;
+basic.showNumber(counter);
+```
 
 ### Why use variables?
 
-Variables help simplify your code. For example, instead of turning on LEDs one by one like this:
+If you want to remember and modify data, you'll need a variable. 
+A counter is a great example:
 
-![](/static/mb/blocks/var-8.png)
-
-You can use a variable (`i`) and a [for loop](/reference/loops/for) to plot the same series of points (`i` is incremented by 1, each time the loop repeats):
-
-![](/static/mb/blocks/var-9.png)
+```blocks
+let counter = 0;
+input.onButtonPressed(Button.A, () => { 
+  counter = counter + 1;
+  basic.showNumber(counter);
+});
+```
 
 ### Local variables
 
 Local variables exist only within the function or block of code where they're defined. For example:
 
-![](/static/mb/blocks/comment-0.png)
+```blocks
+// x does NOT exist here.
+if (led.brightness() > 128) {
+  // x exists here
+  let x = 0;
+}
+```
