I am using arduino Mega and I have a out put in Analog signal.

i got always an error from missing api key for 192.19.12.0

I wonder if you know how to pass 3 different inputs to 3 outputs using function node? So, 1st input would pass to 1st output, 2nd input would pass to 2nd output and so forth

Is this license free and can i use it for real time analysis of signals. Waiting for reply

[@sumitrathod9046]

Yes it is opensource IOT platform you can use it for real time analyis of signal..but should match the output protocol from inbuilt function else you have to make your own function

The device in the link below does signal analysis, supports nodered, ignition edge, azure, and has built in IO. www.tyrionintegration.com/nucleus/
