Hopefully this is the right forum to ask this question. I have a project in mind that will add some features to my car (mitsubishi evo x), but since I've never used an arduino before I want to start on a slightly simpler task. I want to start with simply having the arduino read the vehicle speed off the CAN-BUS and display it to a LCD screen.
My question is, can the arduino be connected directly to the CAN-BUS in some way (not through the ODBII port)? When the project is complete I want it to be more of a permanent install and not interfere with my OBDII port as I use it for data-logging.
