OBDuino is an open source trip computer design based on the Arduino platform.
An OBDuino may be assembled and customised by an electronics hobbyist; it displays information such as instantaneous fuel economy (e.g. miles per gallon, L/100 km or kilometres per litre), engine tuning parameters etc.
OBDuino utilises the On-Board Diagnostics interface found in most modern cars.
The main OBDuino thread[3] on the eccomoder forum was started by jmonroe on 1 June 2008 as a fork of MPGuino discussions.
As of September 2009, the OBDuino32K code credits these developers: Main coding/ISO/ELM: Frédéric (aka Magister on ecomodder.com) LCD part: Dave (aka dcb on ecomodder.com), optimized by Frédéric ISO Communication Protocol: Russ, Antony, Mike Features: Mike, Antony Bugs & Fixes: Antony, Frédéric, Mike The 32K in the obduino32K name differentiates the code targeted at the Atmega328 with 32k flash memory (i.e. Arduino 2009) version from the Atmega168 16k (Arduino 2008) version.
