Usage:
bumper.set_color(color)

Parámetros	Descripción

# Build Used: Super Code Base 2.0
def main():
    # Blink the LED off and on
    while True:
        bumper.set_color(GREEN)
        wait(0.5, SECONDS)
        bumper.set_color(OFF)
        wait(0.5, SECONDS)

start_thread(main)

set_brightness

set_brightness sets how bright the LED Bumper is.

A higher percentage makes the light brighter. A lower percentage makes the light dimmer.

If the LED Bumper is off, setting the light power above 0% will turn the light on.

If the LED Bumper is on, setting the light power at 0% will turn the light off.
