Unplot

Turn off the LED light you say on the LED screen.

led.unplot(0,0)

~hint

Use plot to turn on an LED.

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), then this function will do nothing.

~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: Center off

This program shows a picture on the LED screen, and then turns off the center LED with unplot.
