2 Ultrasonic sensors

Interfacing 2 Ultrasonic Sensors

Interfacing 2 ultrasonic sensors is same as as interfacing ultrasonic sensor but there's a slight change in the code. We'll have give a identity to the ultrasonic sensor as 1 and another as 2, so that the computer can identify to which ultrasonic sensor we are giving the condition(s).

Code

#include <NewPing.h>

int y = 0 ;

int x = 0 ;

#define ECHO_PIN1 3
#define TRIGGER_PIN1 2
#define MAX_DISTANCE1 500// Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

NewPing sonar1(TRIGGER_PIN1, ECHO_PIN1, MAX_DISTANCE1);

#define ECHO_PIN2 9
#define TRIGGER_PIN2 8
#define MAX_DISTANCE2 500// Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

NewPing sonar2(TRIGGER_PIN2, ECHO_PIN2, MAX_DISTANCE2);
void setup()

{

  Serial.begin(9600);

 x = sonar1.ping_cm() ;

 y = sonar2.ping_cm() ;

 }
void loop()

{ 

x = sonar1.ping_cm() ;

y = sonar2.ping_cm() ;

Serial.println(x);

Serial.println(y);
