### Parameters
## Parameters
* a [number](/reference/types/number) that means
how many LEDs to scroll at a time, from right to left or
left to right. If you use a positive number like `2`, the image
will scroll from the right side of the screen to the left.
If you use a negative number like `-2`, the image will scroll
in the other direction. If you use `5` or `-5`, the image
will scroll one **frame** at a time. (A frame is a part of the
image. It is a square with five LEDs on a side). This is
useful for **animation**.
* a [number](/types/number) that means
how many LEDs to scroll at a time from right to left.

* a [number](/reference/types/number) that means
* a [number](/types/number) that means
how many milliseconds to wait before scrolling the amount that
``offset`` says. (1000 milliseconds is one second.) The bigger you
make this number, the slower the image will scroll.
### Example

This program scrolls an image of two arrows five LEDs at a time,
with a pause of 200 milliseconds between each time it scrolls.
