Unplot
Turn off a LED light on the LED screen. Specify which LED using x, y coordinates. Use plot to turn a LED on.
led.unplot(0,0)
Parameters
- x - Number; the x coordinate or horizontal position (0, 1, 2, 3, 4)
- y - Number; the y coordinate or vertical position (0, 1, 2, 3, 4)
If a parameter is out of bounds (a value other than 0-4), 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.
This code turns off centre LED:
led.unplot(2, 2)
Get the LED on/off state
Use the point function to find out if a LED is on or off.
Example: toggle off
This code creates and shows an image on the micro:bit screen, and then clears the centre LED using unplot:
basic.showLeds(`
. . # . .
. . # . .
# # # # #
. . # . .
. . # . .

basic.pause(500)
led.unplot(2, 2)
