Show a string on the [LED screen](/device/screen). It will scroll to left if it's bigger than the screen.
2016-03-26 00:47:20 +01:00
```sig
basic.showString("Hello!")
```
## Parameters
2016-03-26 00:47:20 +01:00
2017-03-16 15:57:41 +01:00
* `text` is a [String](/types/string). It can contain letters, numbers, and punctuation.
* `interval` is an optional [Number](/types/number). It means the number of milliseconds before sliding the [String](/types/string) left by one LED each time. Bigger intervals make the sliding slower.
