I have a problem with; class ultrasonic 'has no member named ranging

Projects Programming
1

mark error and try a lot with several libraries and do not want to know if I'm doing something wrong or something but I mark that error and I can not fix it

#include <Servo.h>
#include <Ultrasonic.h>

Ultrasonic ultrasonic(3,5);
Servo miniservo1;
Servo miniservo2;
int led=7;
int distancia;

void setup()
{
miniservo1.attach(11);
miniservo1.write(0);

pinMode(led, OUTPUT);
}

void loop()
{

distancia = ultrasonic.ranging(CM);

if(distancia <= 20)
{

miniservo1.write(180);

digitalWrite(led, HIGH);
delay(500);
}else{
miniservo1.write(0);

digitalWrite(led, LOW);
}
delay(500);
}

There are multiple libraries for ultrasonics on the Arduino. Where did you get yours from?

What makes you think that you can do this?

distancia = ultrasonic.ranging(CM);

I downloaded them from different sites, and the program did not work for me and I downloaded it from a video, and in the video it is the same and if it works.

No links to the library. No links to the video. No help from me.
