# Point
|
|
|
|
Get the on/off state of a LED on the [LED screen](/device/screen). Specify the LED using x, y coordinates.
|
|
|
|
```sig
|
|
led.point(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 return `false`.
|
|
|
|
### Returns
|
|
|
|
* [Boolean](/reference/types/boolean) - `true` if the LED is *on* and `false` if the LED is *off*
|
|
|
|
### 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: toggle off
|
|
|
|
If `point(1, 1)` returns `true`, then the following code turns off the LED:
|
|
|
|
```blocks
|
|
if (led.point(1, 1)) {
|
|
led.unplot(1, 1)
|
|
}
|
|
```
|
|
