Arduino OBD-II UART Adapter Library & Examples
==============================================
(C)2012-2013 Stanley Huang
The Arduino OBD-II UART Adapter is a product works as an OBD-II to serial UART data bridge with open-source Arduino library provided. Besides providing OBD-II data access, it also provides power supply (converted and regulated from OBD-II port) for Arduino and its attached devices. The adapter can also be used in other embedded systems with serial UART interface.

About the library
-----------------
In current version of the library, following OBD-II PIDs are defined:
Vehicle speed (PID_SPEED)
Engine RPM (PID_RPM)
Throttle position (PID_THROTTLE)
Calculated Engine load (PID_ENGINE_LOAD)
Absolute Engine load (PID_ABS_ENGINE_LOAD)
Engine coolant temperature (PID_COOLANT_TEMP)
Intake temperature (PID_INTAKE_TEMP)
Intake MAP (PID_INTAKE_PRESSURE)
MAF flow pressure (PID_MAF_FLOW)
Fuel pressure (PID_FUEL_PRESSURE)
Fuel level (PID_FUEL_LEVEL)
Barometric pressure (PID_BAROMETRIC)
Ignition timing advance (PID_TIMING_ADVANCE)
Engine running time (PID_RUNTIME)
Vehicle running distance (PID_DISTANCE)
Additional defines can be added to access all OBD-II PIDs which the car's ECU provides.
