Question

You want to blink an LED connected to GPIO pin 23 on Raspberry Pi using Python. Which code snippet correctly blinks the LED once with 1 second ON and 1 second OFF?

Accepted Answer

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(23, GPIO.OUT)
GPIO.output(23, True)
time.sleep(1)
GPIO.output(23, False)
time.sleep(1)

Answer

import RPi.GPIO as GPIO
GPIO.setup(23, GPIO.OUT)
GPIO.output(23, 1)
time.sleep(1)
GPIO.output(23, 0)
time.sleep(1)

Answer

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(23, GPIO.IN)
GPIO.output(23, True)
time.sleep(1)

Answer
