Raspberry Pi - GPIO Basics with Python

Identify the issue in this code snippet:

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

AMissing GPIO.cleanup() call before setup

BGPIO.setmode(GPIO.BOARD) should be GPIO.setmode(GPIO.BCM)

CGPIO.setup requires a pin number as a string, not integer

DPin 17 is invalid in BOARD mode because 17 is a BCM pin number

Step-by-Step Solution

Solution:

Step 1: Understand BOARD mode numbering
In BOARD mode, pin numbers correspond to physical pins on the header.
Step 2: Check pin 17
Physical pin 17 exists, but GPIO 17 is a BCM pin number, not a physical pin number.
Step 3: Conclusion
Using 17 in BOARD mode is incorrect because 17 is a BCM pin number, not a physical pin number.
Final Answer:
Pin 17 is invalid in BOARD mode because 17 is a BCM pin number -> Option D
Quick Check:
BOARD mode expects physical pin numbers, not BCM numbers [OK]

Quick Trick: BOARD mode uses physical pins, not BCM numbers [OK]
