[Solved] Why is the GPIO.cleanup() call in this LED pattern code incorrect?import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(16, GPIO.OUT) GPIO.output(16, GPIO.HIGH) GPIO.cleanup(16) | Raspberry Pi

Why is the GPIO.cleanup() call in this LED pattern code incorrect?

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(16, GPIO.OUT)
GPIO.output(16, GPIO.HIGH)
GPIO.cleanup(16)

AGPIO.setmode() must be called after setup().

BGPIO.output() cannot be called before setup().

CGPIO.cleanup() does not take pin numbers as arguments.

DGPIO.HIGH is not a valid output value.

Step-by-Step Solution

Solution:

Step 1: Understand GPIO.cleanup() usage
GPIO.cleanup() should be called without arguments to reset all pins; passing a pin number is incorrect.
Step 2: Check other function usages
GPIO.output() after setup() and GPIO.setmode() before setup() are correct; GPIO.HIGH is valid.
Final Answer:
GPIO.cleanup() does not take pin numbers as arguments. -> Option C
Quick Check:
cleanup() argument error = GPIO.cleanup() does not take pin numbers as arguments. [OK]

Quick Trick: Call GPIO.cleanup() without arguments [OK]
