New to the forum. I am trying to develop a design that interfaces with a vehicle’s OBD-II port, but one where I can still use my existing Scangauge (OBD-II vehicle monitor). For my initial project, I would like to use the Arduino as a pass-through, like this:
ScanGauge/OBD2 Reader <-> OBD2-to-RS232 Converter <-> ARDUINO <-> RS232-to-OBD2 Converter
<-> Vehicle OBD2 interface.
I am familiar with Obduino and some of the OBD2/Arduino projects out there, but I haven’t seen anything like this and I don’t understand if something like the ELM237 will work in this configuration. Is this doable? Any tips or comments on this idea for a n00b?
