[Solved] Identify the error in this code snippet: import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(24, GPIO.OUT, pull_up_down=GPIO.PUD_UP) | Raspberry Pi

Raspberry Pi - GPIO Basics with Python

Identify the error in this code snippet:

import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(24, GPIO.OUT, pull_up_down=GPIO.PUD_UP)

APin number 24 is invalid

BGPIO.setmode is missing parameter

CCannot set pull_up_down resistor on output pin

DNo error, code is correct

Step-by-Step Solution

Solution:

Step 1: Understand pull_up_down parameter usage
Pull-up/down resistors can only be set on input pins, not output pins.
Step 2: Analyze code
Code sets pin 24 as output but tries to enable pull-up resistor, which is invalid.
Final Answer:
Cannot set pull_up_down resistor on output pin -> Option C
Quick Check:
Pull-up/down only valid for input pins [OK]

Quick Trick: Pull-up/down resistors only work on input pins [OK]
