Make the LED screen as bright as you say when it is turned on.
led.setBrightness(121)value is a number that means how
bright the screen is when it is turned on, from 0 (darkest) to
255 (brightest). For example, the number 127 means the screen is
halfway bright when it is turned on.This program makes the screen brightness 100% (255). Then it turns on
the center LED (2, 2), waits for one second, and then sets the screen
brightness to 50% (128):
led.setBrightness(255)
led.plot(2, 2)
basic.pause(1000)
led.setBrightness(led.brightness() / 2)
