# Toggle
|
|
|
|
Toggle a LED light on the [LED screen](/device/screen), meaning to turn it on (off) if it is off (on). Specify which LED using x, y coordinates.
|
|
|
|
```sig
|
|
led.toggle(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), then 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).
|
|
|
|
### Example
|
|
|
|
This code toggles the centre LED:
|
|
|
|
```blocks
|
|
led.toggle(2, 2)
|
|
```
|
|
|
