# Unplot
|
|
|
|
Turn off a LED light on the [LED screen](/device/screen). Specify which LED using x, y coordinates. Use [plot](/reference/led/plot) to turn a LED on.
|
|
|
|
```sig
|
|
led.unplot(0,0)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* x - [Number](/reference/types/number); the *x coordinate* or horizontal position (0, 1, 2, 3, 4)
|
|
* y - [Number](/reference/types/number); the *y coordinate* or vertical position (0, 1, 2, 3, 4)
|
|
|
|
If a parameter is [out of bounds](/reference/out-of-bounds) (a value other than 0-4), this function will do nothing.
|
|
|
|
### x, y coordinates?
|
|
|
|
The LED screen is made up of 25 LEDs arranged in a 5x5 grid. To figure out the ``x``, ``y`` coordinates, see [LED screen](/device/screen).
|
|
|
|
This code turns off centre LED:
|
|
|
|
```blocks
|
|
led.unplot(2, 2)
|
|
```
|
|
|
|
### Get the LED on/off state
|
|
|
|
Use the [point](/reference/led/point) function to find out if a LED is on or off.
|
|
|
|
### Example: toggle off
|
|
|
|
This code creates and shows an image on the micro:bit screen, and then clears the centre LED using `unplot`:
|
|
|
|
```blocks
|
|
basic.showLeds(`
|
|
. . # . .
|
|
. . # . .
|
|
# # # # #
|
|
. . # . .
|
|
. . # . .
|
|
`)
|
|
basic.pause(500)
|
|
led.unplot(2, 2)
|
|
```
|
