# smiley blocks quiz answers
This is the answer key for the [smiley quiz](/lessons/smiley/quiz).
## 1. Describe what `show LEDs` does
A function that will display an image on the LED screen
## 2. Why is there an extra empty frame after the smiley face?

<br/>
The extra empty image with show LED creates a blinking smiley, allowing the micro:bit to alternate between showing the smiley and the empty screen.
## 3. Draw the image created with this code
```blocks
basic.showLeds(`
. # . # .
. # . # .
. . . . .
# . . . #
. # # # .
`)
```
