1. Circuit diagram

2. GPIO Pin

 

3. Code

1) Use BCM

import RPi.GPIO as GPIO
import time

LED_PIN = 17
led_status = True

GPIO.setmode(GPIO.BCM)
GPIO.setup(LED_PIN, GPIO.OUT)

try:
	while True:
		GPIO.output(LED_PIN, led_status)
		print("LED_Status = ")
		print(led_status)
		led_status ^= True
		time.sleep(5)
		
except KeyboardInterrupt:
	GPIO.cleanup()

2) Use Board

import RPi.GPIO as GPIO
import time

LED_PIN = 11
led_status = True

GPIO.setmode(GPIO.BOARD)
GPIO.setup(LED_PIN, GPIO.OUT)

try:
	while True:
		GPIO.output(LED_PIN, led_status)
		print("LED_Status = ")
		print(led_status)
		led_status ^= True
		time.sleep(5)
		
except KeyboardInterrupt:
	GPIO.cleanup()

 

4. ETC

 GPIO.setup(11, GPIO.OUT)
 #or
 GPIO.setup(11, GPIO.IN)
