+# Point Brightness
+
+Read the brightness of a LED on the [LED screen](/device/screen).
+
+```sig
+led.pointBrightness(0,0);
+```
+
+## Parameters
+
+* ``x`` is a [number](/types/number) that means the
+  horizontal spot on the LED screen (from left to right: 0, 1, 2, 3,
+  or 4)
+* ``y`` is a [number](/types/number) that means the vertical
+  spot on the LED screen (from top to bottom: 0, 1, 2, 3, or 4)
+
+If a parameter is [out of bounds](/reference/out-of-bounds) (a value
+other than 0 to 4), this function will return `false`.
+
+## Returns
+
+* a [number](/blocks/logic/number). If it is `true`, that means the LED is on. If it is `false`, that means the LED is off.
+
+## ~hint
+
+The LED screen is a solid square of LEDs with five LEDs on each side.
+To learn more about how you number the LEDs with ``x`` and ``y``
+coordinates, see [LED screen](/device/screen).
+
+## ~
+
+## Example: Toggle off
+
+This program turns the center LED (2, 2) off it is not bright enough.  (If
+it is already off, this program leaves it off.)
+
+```blocks
+if (led.pointBrightness(2, 2) < 100) {
+    led.unplot(2, 2)
+}
+```
