![]() The fuel level, door sensors, odometer, and many more parts of a car have to communicate with each other somehow, and CAN BUS is what they used to do. For example, they are found in vehicles, farming equipment, industrial environments, etc. CAN is a serial communication bus designed for industrial and automotive applications. the engine control unit, airbags, audio system, etc. Today, you can find up to 70 ECUs in a modern car, e.g. These devices are also called Electronic Control Units (ECU) and they enable communication between all parts of a vehicle. Getting started with CAN-BUS with ArduinoĬAN stands for Controller Area Network, it is used to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer which allows for control and data acquisition.I hope that you’ll get a better understanding of it through this blog: Ever heard of CAN-BUS but don’t exactly know what it does? Fret not! We will be discussing everything about CAN-BUS today.
