[Solved] Identify the error in this code snippet:import RPi.GPIO as GPIO GPIO.setmode(GPIO.BOARD) GPIO.setup(11, "OUT") GPIO.output(11, True) GPIO.cleanup() | Raspberry Pi

Raspberry Pi - GPIO Basics with Python

Identify the error in this code snippet:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(11, "OUT")
GPIO.output(11, True)
GPIO.cleanup()

ACalling GPIO.cleanup() before output.

BUsing string "OUT" instead of GPIO.OUT in setup.

CMissing GPIO.setwarnings(False) before setup.

DNot importing time module for delays.

Step-by-Step Solution

Solution:

Step 1: Check GPIO.setup() syntax
The direction argument must be GPIO.OUT or GPIO.IN, not a string like "OUT".
Step 2: Verify other lines
GPIO.setwarnings() is optional, cleanup is correctly called last, and time module is not needed here.
Final Answer:
Using string "OUT" instead of GPIO.OUT in setup. -> Option B
Quick Check:
Pin direction must be GPIO.OUT, not "OUT" [OK]

Quick Trick: Use GPIO.OUT constant, not string "OUT" [OK]
