= HCSR04 ultrasonic sensor Library for Arduino =

HCSR04 is an Arduino library HCSR04 Sensors

Documentation

Documentation for the library is on the Github Project Pages

basic example

#include <HCSR04.h>

HCSR04 hc(2,3);//initialisation class HCSR04 (trig pin , echo pin)

void setup()
{ Serial.begin(9600); }

void loop() 
{ Serial.println( hc.dist() ); } //return current distance (cm) in serial

if you want use a multiple sensor

#include <HCSR04.h>

HCSR04 hc(2,new int[6]{5,6,7,8,9,10},6);//initialisation class HCSR04 (trig pin , echo pins, number of sensors)

void setup()
{ Serial.begin(9600); }

void loop()
{ for (int i = 0; i < 6; i++ ) {Serial.println( hc.dist(i) );} }//return curent distance (cm) in serial for sensor 1 to 6
