First example in dummies guide has error : NameError: name GPIO is not defined

Question

Raspberry Pi for Dummies. Page 49

Line 7 GPIO.setmode(GPIO.BCM)

error: NameError: name GPIO is not defined

we've checked it's definately the letter 'O' not a zero. Either the code isn't right or the import RPi.GPIO isn't correct.

`we tried python and python3

Any ideas?

Post the code you are attempting to run together with the actual error message (cut & paste). — joan, Jan 10, 2017 at 14:00

I am not sure what the full example looks like but ti should look like this.

#external module imports
import RPi.GPIO as GPIO

#pin setup
GPIO.setmode(GPIO.BCM)

the issue was as GPIO missing. Thanks, it works now!

You are not providing all your code, so I'm not sure what you have imported, however, after doing

import RPi.GPIO as GPIO

the statement

GPIO.setmode(GPIO.BCM)

should work. If you forgot the as GPIO part, it would still work but you'd have to type

RPi.GPIO.setmode(RPi.GPIO.BCM)
