Question

You want to control two LEDs connected to GPIO pins 17 and 27. Which Python code correctly turns on both LEDs using BCM numbering?

Accepted Answer

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)
GPIO.setup(27, GPIO.OUT)
GPIO.output(17, GPIO.HIGH)
GPIO.output(27, GPIO.HIGH)

Answer

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(17, GPIO.OUT)
GPIO.setup(27, GPIO.OUT)
GPIO.output(17, True)
GPIO.output(27, True)

Answer

import RPi.GPIO as GPIO
GPIO.setup(17, GPIO.OUT)
GPIO.setup(27, GPIO.OUT)
GPIO.output(17, 1)
GPIO.output(27, 1)

Answer

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.IN)
GPIO.setup(27, GPIO.IN)
GPIO.output(17, GPIO.HIGH)
GPIO.output(27, GPIO.HIGH)
