NewPing library

Solved
1

Hi, I’m making a project with esp8266 nodemcu, but when I upload the code Arduino throws this warning:
WARNING: library NewPing claims to run on (avr, arm) architecture(s) and may be incompatible with your current board which runs on (esp8266) architecture(s).

I looked for NewPing library compatible with esp8266, but didnt find anything. Any advice?

forget NewPing lib, it is useless!
let us show your sketch

Here it is. What can I use instead of NewPing?

#include <ESP8266WiFi.h>

delete newping

this is the code to get distance from sensor

  digitalWrite(TRIGGER, LOW);
  delayMicroseconds(2);

  digitalWrite(TRIGGER, HIGH);
  delayMicroseconds(10);

  digitalWrite(TRIGGER, LOW);
  duration = pulseIn(ECHO, HIGH);

  distance = ((duration / 2) / 29.1) * 10;

And here is an example i made for the Ultrasonic sensor… As I already posted in your other topic.
