How to Build a CAN Bus System with Arduino and MCP2515 CAN Modules

In this tutorial, I'll guide you through creating a CAN Bus system using MCP2515 CAN modules with Arduino. We'll be using three Arduino Nanos with sensor shields, an Arduino Uno, and four MCP2515 CAN modules to set up a functional CAN network.

In this video, you’ll learn:

How to connect MCP2515 CAN modules to Arduino
How to install the MCP2515 library and sample code
How to configure unique CAN-IDs for each Arduino Nano
How to send and receive CAN messages with Arduino

By the end of this video, you’ll be able to monitor CAN messages using the Serial Monitor and understand how to expand your project for more advanced applications.
