This example uses the Adafruit’s digitalio package to create a DigitalInOut object.

The LED should blink with on and off times of a half second.

import time
import board
import digitalio

led = digitalio.DigitalInOut(board.IO0)
led.direction = digitalio.Direction.OUTPUT

while True:
    led.value = True
    time.sleep(0.5)
    led.value = False
    time.sleep(0.5)
