[Solved] Which of the following is the correct syntax to import the GPIO library and set pin 23 as input? — Ans: import RPi.GPIO as GPIO GPIO.setup(23, GPIO.IN) | Raspberry Pi

Raspberry Pi - GPIO Basics with Python

Which of the following is the correct syntax to import the GPIO library and set pin 23 as input?

Aimport RPi.GPIO as GPIO GPIO.setup(23, GPIO.IN)

Bimport GPIO GPIO.setup(23, GPIO.OUT)

Cimport RPi.GPIO GPIO.setup(23, GPIO.OUT)

Dimport RPi.GPIO as GPIO GPIO.setup(23, GPIO.OUT)

Step-by-Step Solution

Solution:

Step 1: Import library correctly
The standard import is 'import RPi.GPIO as GPIO'.
Step 2: Set pin 23 as input
GPIO.setup(23, GPIO.IN) sets pin 23 as input.
Final Answer:
import RPi.GPIO as GPIO GPIO.setup(23, GPIO.IN) -> Option A
Quick Check:
Import and setup input pin correctly [OK]

Quick Trick: Use 'import RPi.GPIO as GPIO' and GPIO.IN for input [OK]
