Plot Brightness

Turn on a LED light with a specific brightness on the LED screen.

led.plotBrightness(0,0, 128);

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)
• brightness` is a number that represents the brightness of the LED, from 0 (off) to 255 (full brightness)

If a parameter is out of bounds (a value other than 0 to 4), then this function will do nothing.

Example: One LED

This program turns on the bottom right LED at 50% brightness

led.plotBrightness(2, 2, 128)

Example: Square

This program uses a for loop and the plotBrightness function to make a square around the edges of the LED screen.

for (let i = 0; i < 5; i++) { led.plotBrightness(0, i, 64) led.plotBrightness(4, i, 128) led.plotBrightness(i, 0, 172) led.plotBrightness(i, 4, 255) basic.pause(500) }
