Arduino OBD2 ELM327 Simulator

Arduino OBD2 ELM327 Simulator.
OBD2 관련 개발을 위한 Simulator를 제작하였습니다.
To develop OBD2 prototype, making OBD2 Simulator before start develop process.
Arduino acts like car's ecu. When ELM327 request data to arduino, then arduino reply the data like car's ecu. User can modify parameter on code, then pad display constant's value.
I just set the parameter random or periodically.
