To use the MCP2515 Module with an Arduino, you will need to connect the module to Arduino using the SPI interface. It is commonly used to provide an interface between a microcontroller and external hardware, such as sensors and actuators. you can use the MCP2515 library to transmit and receive data over the CAN bus.

You can use an Arduino board to complete tasks such as sending messages, receiving messages, and monitoring the condition of the CAN bus.

A circuit diagram for an MCP2515-based design below shows the connections between the MCP2515, the CAN transceiver, with Arduino microcontroller, and the other components in the system.

The transmitter and receiver Parts are connected to the CAN Bus Module (MCP2515) by their CAN-H and CAN-L pins.  The following image shows you communication between two Arduino over CAN Protocol.

Before starting on the coding part of the project, we need to install the MCP2515 CAN Bus Library to the Arduino IDE. Download and install CAN Library

Connect the Jumper at the end nodes only.
