How do I add button resetting angel of Ultrasonic Sensor here is my code hope you add code for button thanks!
// C++ code
//

#include <Servo.h>
#define trigPin 3
#define echoPin 2
Servo servo;
int sound = 250;
void setup() {
Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
servo.attach(4);
}
void loop() {
long duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
if (distance < 100) {
Serial.println("the distance is more than 100");
servo.write(100);
}
else {
servo.write(0);
}
if (distance < 0 || distance <= 0){
Serial.println("The distance is less than 0");
}
else {
Serial.print(distance);
Serial.println(" cm");
}
delay(500);
}

here is I'm trying to fix

#include <Servo.h>

Servo myservo; // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0; // variable to store the servo position
int button = 8;
int trigpin = 11;
int echopin = 10;

void setup() {
myservo.attach(9); // attaches the servo on pin 9 to the servo object
pinMode(button, INPUT);
pinMode(trigpin, OUTPUT);
Serial.begin(9600);
pinMode(echopin, INPUT);

}

void loop() {
long x, inches;
int buttonstate = digitalRead(button);
while(buttonstate == 1){
inches = microsecondsToInches(x);
delay(1000);
Serial.print("Inches = ");
Serial.println(inches);

  if(inches > 18 && inches < 120){

          for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
              // in steps of 1 degree
              myservo.write(pos);              // tell servo to go to position in variable 'pos'
              delay(15);                       // waits 15 ms for the servo to reach the position
          }
          for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
                myservo.write(pos);              // tell servo to go to position in variable 'pos'
                delay(15);                       // waits 15 ms for the servo to reach the position
          }
  }
    else {
     digitalWrite (pos, LOW);
    }

}//whileclose

}//coidclose

double microsecondsToInches(long duration){
digitalWrite(trigpin, LOW);
delayMicroseconds(2);
digitalWrite(trigpin, HIGH);
delayMicroseconds(10);
digitalWrite(trigpin, LOW);
duration = pulseIn(echopin, HIGH);
return duration /74/2;
}

Welcome to the forum

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination

I don't understand what you mean by "resetting". What do you want your sketch to do?

?!? 'pos' is NOT a pin number ?!?

Just a little tip for you @z4y
