I am a beginner in Node-RED

I have installed Node-RED and the Jhonny -five library on my beaglebone black to read or write its GPIOs.

I have made a simple flow to turn on the user led USR3 using a Jhonny -five node. According to the GPIO information , this led corresponds to GPIO2\_24 on the BBB, but I can't get the led to turn on.

When executing the flow , at the bottom of the Jhonny -five node the word "connected" appears, but the led is not turned on.

I have the doubt about how the pin name should be written in the Jhonny -five field.

Could someone help me to solve this doubt?

Thanks
