Alright, So i was looking for a very small display, just to show me couple of basic items i need to know from the ECU such as oil pressure and oil temp ect. basically everything out there was way over spec and price for this type of application. I had an arduino uno laying around and decided to play with that a bit. so what we have here is essentially, arduino uno, serial lcd and a can shield. https://www.sparkfun.com/products/11021 https://www.sparkfun.com/products/10039 http
