This Article is to make readers to explore about how to interface CAN Bus with Arduino which is used in the Communication of Sensors, Actuators and controllers in a car.This project helps in understanding the insights of CAN protocol interfacing with Arduino. Controller Area Network or CAN protocol is a methodology of communication between various electronic devices like engine management systems, gear control, active suspension, ABS, lighting control, air conditioning, airbags, central locking etc. embedded in an automobile. For further learnings refer this article.

Much like the name suggests, DC motor controllers control the speed and direction of a DC motor. To change the direction of the motor, however, the supply it receives must be reversed. And, to vary the DC motor speed, a pulse-width modulation (PWM) signal or wave must be applied to it.  As the pulse width…
