Sensor-Based E-Waste Lion Model with Sound & Motion Response

This innovative project is a robotic lion model made entirely using e-waste and recycled materials. It uses an ultrasonic sensor to detect nearby objects (within 2 meters), responds with a realistic roaring sound, and wagging tail movement through a servo motor. Designed to encourage sustainability and creative reuse of discarded electronics, this project blends environmental awareness with practical electronics and coding skills, making it perfect for student learning and STEM outreach.

Story

Title:

Sensor-Based E-Waste Lion Model with Sound & Motion Response

Introduction:

This project is an innovative robotic lion made entirely from electronic waste materials, designed to mimic a lion’s real-life behavior. It is equipped with sensors and programmed using an Arduino to detect human presenceroar, and move its tail. The aim is to encourage eco-friendly innovation and hands-on STEM learning.

Features & Design:

 

Code
  • Code sensor based robotic lion using E-waste
