Answer 1

Answer:

Check the explanation

Explanation:

import time

import board

from digitalio import DigitalInOut, Direction, Pull

led = DigitalInOut(board.D13)

led.direction = Direction.OUTPUT

# For Gemma M0, Trinket M0, Metro M0 Express, ItsyBitsy M0 Express, Itsy M4 Express

switch = DigitalInOut(board.D2)

# switch = DigitalInOut(board.D5) # For Feather M0 Express, Feather M4 Express

# switch = DigitalInOut(board.D7) # For Circuit Playground Express

switch.direction = Direction.INPUT

switch.pull = Pull.UP

while True:

# We could also do "led.value = not switch.value"!

if switch.value:

led.value = False

else:

time.sleep # debounce delay
