The Mechatronics System Design Virtual Lab has been developed to provide an interactive and realistic environment for understanding the integration of mechanical, electronic, and control components. This virtual platform enables learners to explore how different sensors and actuators are interfaced with the Arduino Uno microcontroller and how these elements work together to form a complete Mechatronic system.

In this lab, students can perform sensor connections, observe signal responses, and understand the working principles without the need for physical hardware. The virtual setup replicates real-world circuit behaviour, allowing users to build, modify, and test Mechatronic circuits safely and efficiently.

The lab incorporates a variety of commonly used sensors, including LED indicators, switches, an IR sensor, a temperature sensor, an encoder, and a proximity sensor. Each sensor demonstrates its specific method of sensing and signal generation, offering learners hands-on experience with digital and analog interfacing. The Arduino Uno acts as the central controller, reading sensor inputs, processing data, and generating appropriate output signals based on programmed logic.

Through this virtual environment, learners gain practical insights into sensor operation, microcontroller programming, and system integration-key skills essential for designing and developing modern mechatronic systems. The lab enhances conceptual understanding, improves debugging skills, and prepares students for real-time applications in robotics, automation, and embedded system design.
