Nodered can't turn on/off digital pin

I have installed nodered whit the script.

I'm trying to run my firs flow, i read this guide

I can't tur on or off my led, it's always on.

Any suggestion?

welcome to the forum @faprile

Are you sure you have it on the correct pin? Pin number can confusing.

Does the status display by the node in the editor show it changing?

Please post a screenshot of the GPIO node configuration (you can paste an image here directly). Also connect a debug node showing what is going into the GPIO node and show us what it shows.

How did you install node-red? Did you use the recommended script?

thank for your reply
