  • This is a good tutorial and I've even used it personally for reference while working on my own OBDII car display. I appreaite the effort to write this! Although, I went a slightly different route. A good alternative would be to get an HC-05 or similar Bluetooth module for the Arduino and a Bluetooth OBDII adapter. Both are very cheap on sites like Amazon or eBay. I'm talking less than $10 for a bluetooth OBD adapter and around the same for a HC-05. You may also need a logic level converter between the Arduino and bluetooth module like I did, since the Arduino is 5V and the module is 3.3V. The advantage of this method is that you don't have to rip an adapter apart and there's need to worry about running wires.
