Footstep Piezo Power Generator Arduino Project

Road Footstep Piezo Power Generator Arduino Science Project

The Road Footstep Piezo Power Generator Arduino Science Project is an educational energy-harvesting model designed to demonstrate how mechanical pressure from footsteps or vehicle movement can be converted into electrical energy. This project uses multiple 35mm piezoelectric discs to generate pulsed electrical output when pressure is applied. The generated energy is rectified, regulated, and stored in a dual 18650 Li-ion battery pack, making it suitable for low-power applications and live demonstrations.

An Arduino Uno R3 controls system monitoring and visualization. A 16×2 I2C LCD displays real-time voltage and system status, while a white LED provides a clear visual indication of energy generation. LED brightness varies directly with the amount of pressure applied to the piezo sensors, helping students easily understand the relationship between mechanical force and electrical output. This project is ideal for science fairs, classroom experiments, DIY learning, and technology demonstrations by Bigyan Project.
