6.1 Introduction

In this module, we will learn to make Clap controlled car.

This Clap Controlled car will move or react according to the claps.Let me first tell you about the main working principle of this robot:

• When you CLAP Once the car will go Forward.
• When you CLAP Twice the car will go Backward.
• When you CLAP Thrice the car will go Left
• When you CLAP for the Fourth Time the car will go Right.

In this project, we will use sound sensor module with Arduino Uno. A sound sensor is defined as a module that detects sound waves through its intensity and converting it to electrical signals. The sound sensor has a thin piece of material called a diaphragm that vibrates when hit by sound waves (similar to how your eardrum vibrates when hearing sound). The vibration of the diaphragm is converted by the sensor into an electrical signal that is sent to the Arduino Uno.
