Hi!

I'm using IOT2040 running node-red application and I want to implement a basic program to run a function when one of the GPIO receives 3,3 V.

I have installed node-red-contrib-iot2000 nodes to use the GPIO ,but when I connect the digital input 3,3V nothing happens.

I would like to ask you for help!

Enclosed you can find two screenshots of my program

thank you!

hi,

I connected the IOT like this. (Enclosed you can found the picture)

When I plug and unplug the wire always the value keeps in 1.I don't see any change. The refresh time is set in 100ms

@bergmanu: Yes, I downloaded the nodes from this link, and the jumper from IOREF is set correctly to 3.3V

Thanks

On a more important note, I think your IOT doesn't see the change in the interface but rather ignores it.

See this documentation on page 14 for further details. The switch in your picture is still on the default position.

Thank you! I solve the problem. I thought that the IOT worked as a raspberry pi but it works different

Thank you for your help!
