|
|
|
|
## 2. Draw which LEDs are ON after running this code and the random number returned is 0
|
|
|
|
```blocks
|
|
let img = images.createImage(`
|
|
. . . . . # # # # # . . . . #
|
|
. # # # . # . . . # # # . # .

`)
|
|
let offset = Math.random(3) * 5
|
|
img.showImage(offset)
|
|
```
|
|

## 3. Draw which LEDs are ON after running this code with an offset of 5. This would occur if the random number returned is 1.
|
|
|
|
```blocks
|
|
let img_ = images.createImage(`
|
|
. . . . . # # # # # . . . . #

let img_1 = images.createImage(`
|
|
. . . . . # # # # # . . . . #
