Hi.
Did you deploy your application?
Are you sure your LED is connected to Pin 18? The Raspberry Pi Pico GPIOs sometimes can be a bit difficult to locate.
Do you get any errors?

The LED is connected to Pin 18, I am pretty sure. There were no errors generated from Node-Red.
So wondering why Node-Red is not communicating with Pi

Hi again.
 
Have you tried a different GPIO pin?
Can you show me a printscreen of your flow and the settings of the nodes?
 
To share a picture, upload it to google drive or dropbox, for example and then share a link to the files.

Thanks very much, I have sorted it out by changing the PIN.

However, I am trying to implement a schedule trigger using time such as;
start time: 7 pm
stop time: 7 am
How do I implement this using Node-Red? or what other ways can this be achieved?
Regards

Hi again.
That’s explained in the Smart Home eBook.
See Unit 8.3 and Unit 8.4.
 
I hope this helps.

Thanks, I have noted that.

Great.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
