In order to realize the special requirements of the instrument display system for all-terrain racing

a multi-function instrument system based on Arduino is designed. On the basis of analysis on functions of the racing instrument system

the Arduino NANO development board is selected. By designing the sensor processing circuit and compiling relevant program

information collection and display of basic functions of the engine

the vehicle speed

the belt temperature

and extended functions of pulse and track records of the driver during the racing work can be realized. It is simple

easy to operate and reliable. Test result shows that the system can meet the needs of competition and related testing

and can be used as a relevant experimental platform for beginners.
