This will be the most comprehensive OBD-II data logger kit and also the biggest in size as it is based on Arduino MEGA2560. Te kit consists of:
Just bumped into a website introducing a home-brew Arduino GPS tracker made up with a GPS and GSM shield.
Right now an enhanced version for the Arduino OBD-II data logger kit is under development. The new kit will feature 10Hz GPS logging via MTK3329, OBD-II data logging via Arduino OBD-II adapter, and 3-axis accelerometer sensor data logging via MPU6050 embedded inside the adapter. What is more interesting is that the new kit will base on a variant of Arduino, named Microduino, with smaller size and better capability, stackable like normal Arduino, making the whole kit small and tidy.
For those who have previously ordered the Arduino OBD-II data logger kit, there is no worry about your investment, as the most worthy parts in the kit (OBD-II adapter and I2C OLED module) are still usable in the new kit, and there will also be an upgrade pack (including the new Microduino parts and MTK3329 GPS receiver) by the time the new kit is ready for order.

After working out and merchandising the Arduino OBD-II adapter, I was thinking of putting up some kits based on the adapter with which people can start playing Arduino with cars more easily. A useful application as my initial approach is a OBD-II data logger device which reads out sensor data from vehicle and records the data on mass storage (e.g. SD card). Besides data logging, it better also displays some realtime data and states on a screen. The logged data also needs something to illustrate, possibly into a chart. All these thoughts brought up the Arduino OBD-II data logger kit and this website.
This maintenance update mainly fixed the library’s compatiblity issue with Arduino Leonardo and other ATMega32U4 based new boards. The folder structure has also some adjustments. The shield library files which demo sketches use are now placed in their sub-folders respectively. A new demo sketch was added in the release package (source code) which drives a tiny cool OLED module to make a dashboard for the car. The module can be ordered here.
I just updated the OBD-II library for Arduino. The update improves initialization routine and added compatibility with adapters of new revision.
The latest source code has been committed to SF.net subversion repository.
The whole thing is still in early stage. The idea is converting logged data file into a KMZ file and a HTML file which can be loaded and viewed in web browser.
This is a GPS module test sketch for Arduino based on a LCD1602 shield. You can either save it to local INO file and build width Arduino IDE (TinyGPS library is required). You can also compile it online into a HEX file and upload to Arduino with AVRDUDE or other uploading utilities.
The Arduino OBD-II adapter now comes with accelerometer built-in . This demo video shows an Arduino with RGB LED matrix rendering data of the accelerometer.
This ought to be a work putting together most of my previous research and efforts. The hardware is made up of:
