I am not sure what I am doing wrong here.

I found this guide on but it's not working for me. The program does not output any errors but the LED doesn't light up.

I have and LED with + on GPIO 12 and - on GPIO 6 with a 100 Ohm resistor. This is shown in the images below:

Here is the code I am using

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

GPIO.setup(12,GPIO.OUT)
GPIO.output(12,GPIO.HIGH)

time.sleep(3)

GPIO.output(12, GPIO.LOW)
GPIO.cleanup()
  • I was able to make it work by changing 12 to 18... however when I count the pins it is actually 12? Why is this? – Bruce Levy Dec 3 '18 at 6:45

Thats because by using 'GPIO.setmode(GPIO.BCM)' you are specifying the BCM numbering convention. GPIO 18 is actual pin number 12.
