# Show Number
Show a number on the [LED screen](/microbit/device/screen), one digit at a time (scrolling from left to right)
~~~~sig

~~~~
### Parameters
* value - a [Number](/microbit/reference/types/number)
* (optional) interval (ms) - [Number](/microbit/reference/types/number); the time (in milliseconds) before scrolling by one LED; the larger the number, the slower the scroll
### ~

~~~~

### Example: count to 5
This example uses a [for](/microbit/reference/loops/for) loop to show numbers ``1`` through ``5`` on the screen:
~~~~blocks
for (let i = 0; i < 5; i++) {
basic.showNumber(i + 1)
basic.pause(200)
}
~~~~
