Any chance we can have the documentation files updated to show more info, maybe even examples? I’m trying to get a sonic sensor to output (eventually) to a led bar, when I open the hc-sr04-ultrasonic-range documentation, it tells me it outputs a Last measured distance in meters, but is this a digital signal, analog, and how can I connect this to something useful to get a bar graph display?

Connect it to a watch node and run in debug mode and you will see that it returns a number.

That was awesome! I was able to change the code so I have full use of the sonic sensors range. Thanks!
