What will be the output behavior of this code controlling an LED on pin 7?

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
GPIO.setup(7, GPIO.OUT)
for i in range(3):
    GPIO.output(7, GPIO.HIGH)
    time.sleep(1)
    GPIO.output(7, GPIO.LOW)
    time.sleep(1)

AThe LED will stay on continuously for 3 seconds

BThe LED will blink on and off 3 times with 1 second intervals

CThe LED will blink rapidly without delay

DThe program will cause a runtime error

Step-by-Step Solution

Solution:

Step 1: Analyze the loop and GPIO commands
The loop runs 3 times, turning the LED on, waiting 1 second, off, then waiting 1 second.
Step 2: Understand the timing and LED behavior
This causes the LED to blink on and off 3 times with 1 second intervals.
Final Answer:
The LED will blink on and off 3 times with 1 second intervals -> Option B
Quick Check:
Loop with sleep controls LED blink count and timing [OK]

Quick Trick: Loops with sleep create timed LED blinks [OK]

Common Mistakes:

Ignoring sleep delays
Assuming continuous ON
Confusing HIGH/LOW states
