Hey guys so I’ve been working on a data logger and have gotten everything to work except the OBD part.
When I use the example, the setup works fine. The arduino reads the RPM and lights up the LED if it exceeds 1000rpm. (I know the example I posted says 3000)
However, when I try to read the RPM in my sketch, it will just report 0 and not the RPM. Any ideas?
