Plot
Turn on the LED light you say on the LED screen.
led.plot(0,0);
~hint
Use unplot to turn off 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: One LED
This program turns on the bottom right LED.
led.plot(4, 4)
Example: Square
This program uses a for loop
and the plot function
to make a square around the edges of the LED screen.
for (let i = 0; i < 5; i++) {
led.plot(0, i)
led.plot(4, i)
led.plot(i, 0)
led.plot(i, 4)
basic.pause(500)
}
~hint
Use the point function to find out if an LED is on or off.
