Measuring Voice Speed With Arduino Mega 2560

Introduction

• In this article I will explain about measuring Voice Speed with Arduino Mega 2560.
• It can be used to identify the voice of the speed.
• This works in the same way a bat uses high pitched tones to navigate in the dark. 

Parts

• Arduino Mega 2560
• Ultra sonic
• Hookup wires

Ultrasonic Sensor (HC-SR04):

 
 Figure 1: Ultrasonic Sensor

• It is used to produce the high frequency sound effect.
• It can measure the signal from the sender to the receiver.
• The echo to be determined from the object.

We can fix the Ultrasonic Sensor (HC-SR04):

• Hospital for medicine,
• Industry,
• Home etc. 

Connection:

• Connection from Sensor to Arduino Board:
• Connect the Triger pin to digital pin 03 of board. 
• Connect the Echo pin to digital pin 04 of board.
• Connect the Vcc pin to the 5V of board.
• Connect the Gnd pin to the Gnd of board.

Programming: 

int trigPin=03; //Sensor Trip pin connected to Arduino pin 13
int echoPin=04;  //Sensor Echo pin connected to Arduino pin 11
float pingTime;
float speedOfSound;
int targetDistance=6; //Distance to Target in inches
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);

}

void loop() {
  // put your main code here, to run repeatedly:

  digitalWrite(trigPin, LOW); //Set trigger pin low
  delayMicroseconds(2000); //Let signal settle
  digitalWrite(trigPin, HIGH); //Set trigPin high
  delayMicroseconds(10); //Delay in high state
  digitalWrite(trigPin, LOW); //ping has now been sent

  pingTime = pulseIn(echoPin, HIGH);  //pingTime is presented in microceconds

  speedOfSound = (targetDistance*2)/pingTime*(1000000)*3600/63360;        //converts to miles per hour
  Serial.print("The Speed of Sound is: ");
  Serial.print(speedOfSound);
  Serial.println(" miles per hour");
  delay(1000);
  }

 Explanation:

• In this article I have explained about measuring voice speed.
• It can work under the trig condition side.
• When the distance is in the over level it can measure the distance in the target inches.
• If the target is 6 inches they need 12 inches.
• The target place is 6 and return place is 06.
• The speed of the range is displayed in the serial monitor.
