Project Information

  • Category: Embedded Systems / Robotics
  • Tools: LM393 Sound Sensor, Microcontroller (Arduino), L298N Motor Driver
  • Project Date: November 2024
  • Status: Completed

Key Deliverables

  • Built a hands-free robotic car controlled entirely by audio input.
  • Implemented signal processing logic to differentiate between single and multiple claps.
  • Integrated LM393 sound sensor for reliable environmental input detection.
  • Programmed microcontroller for directional movement based on clap sequence.

Detailed Description

The Clap-Controlled Car project is an introduction to embedded systems and robotics, utilizing sound detection as a command input. The LM393 sound sensor converts claps into usable digital signals for the microcontroller.

The microcontroller interprets these signals using time-based logic to differentiate between 1-clap, 2-clap, and multi-clap commands. These commands control an L298N motor driver to navigate the robotic car.

This project demonstrates practical skills in sensor interfacing, signal processing, and motor control — core areas in embedded electronics.
