Hi,
Thanks for your quick answer!
My car is a Seat Ibiza TDI (Diesel) from year 2000.
I've already ordered this: Arduino Nano, HD44780 LCD, MC33290 IC, 2N3906 transistor and two resistors.
I deduced my car's OBD protocol was ISO since its OBD plug has 12V, GND and ISO-K pins. I could also confirm it
here.
So far, so good
Just a few minutes ago I found
this.
This is ODBuino32K's source code, right?
The main question is: after assembling all the hardware parts how should I proceed to "send" OBDuino32K to the Arduino?
