Ultrasonic Sensor

Introduction

This project shows how to make the distance a meter using Ultrasonic and Arduino. We use Arduino IDE for coding.

The Ultrasonic sensor uses a NewPing library.

NewPing

• After downloading the NewPing library, extract it.

• You can see a NewPing folder.

• Copy the folder and paste it in C:\Program Files (x86)\Arduino\libraries.

Code

#include <NewPing.h> 
const int TriggerPin = 11; 
const int EchoPin = 12
; 
NewPing sonar(TriggerPin, EchoPin, 100); 
void setup() { 
 Serial.begin(9600); 
} 
void loop() { 
 int cm = sonar.ping_cm(); 
 Serial.println(cm); 
 delay(250); 
} 

After uploading this code and NewPing library:

• Restart your Arduino IDE

• Open Serial monitor 9600 baud
