This paper presents a cost-effective and automated system for verifying Malus’s Law using an Arduino microcontroller and a Light Dependent Resistor (LDR). Traditional setups often rely on photodiodes and manual data recording, making them less suitable for modern educational environments. In contrast, the proposed system integrates Arduino with Python-based real-time graphing, reducing observational errors and streamlining the experiment. The setup not only enhances accuracy but also promotes hands-on learning, making it ideal for ICT (Information and Communication Technology)-enabled classrooms. Experimental results closely align with the theoretical cosine-squared (cos²θ) model, validating the system's reliability. This approach offers a practical, scalable, and affordable solution for physics laboratories and STEM (Science, Technology, Engineering, and Mathematics) education.
