Point Brightness

Read the brightness of a LED on the LED screen.

led.pointBrightness(0,0);

Parameters

x is a number that means the horizontal spot on the LED screen (from left to right: 0, 1, 2, 3, or 4)
y is a 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 (a value other than 0 to 4), this function will return false.

Returns

a 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.

~

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.)

if (led.pointBrightness(2, 2) < 100) {
    led.unplot(2, 2)
}
