Plot
Turn on a LED light on the LED screen. Specify which LED using x, y coordinates. Use unplot to turn a LED off.
led.plot(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), then 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 on the centre LED:
led.plot(2, 2)
Get the LED on/off state
Use the point function to find out if a LED is on or off.
Example: a square
The following example uses a for loop and the plot function to turn on the LED lights along the edge of the screen, making a square:
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)
}
