This Research on Project focuses on the development of a real-time automotive dashboard system using the CAN (Controller Area Network) communication protocol. The system consists of two electronic control units, Node A and Node B, both based on the LPC2129 microcontroller. Node A collects input data from a temperature sensor (MCP9700), a potentiometer used as a speed sensor, and multiple control switches for indicators and headlights. The acquired data is processed, encoded into CAN frames, and transmitted through the CAN bus. Node B receives and decodes the CAN messages to extract speed, temperature, and indicator status information. The decoded data is displayed on a 16×2 alphanumeric LCD in real time. The CAN protocol ensures reliable, high-speed, and error-free communication between the nodes. This system significantly reduces wiring complexity, cost, and overall vehicle weight. The design is modular and scalable, making it suitable for future automotive and industrial dashboard applications.Keywords: Keywords are important word in paper Example Weather Prediction, forecast accuracy
