How to break a for loop half way? Emergence!

I got two infrard sensors, just want the motor to turn using a list of angles when the infrard sensor detects a signal, and stop turning immediate once the signal gone. However I can't break out the loop and motor continues to turn until the list ends.

#include <Servo.h>
Servo servoJaw; 
int servoPin1 = 3;
int IRSensor1 = 2;
int IRSensor2 = 7;
int time=0;
int jawlist[] = {
  0,0,90,0,90,0,90,0,180,180,  //18
  0,90,0,90,0,180,180,0,90,180,  //28
};

void setup() {
  servoJaw.attach(servoPin1);
  pinMode (IRSensor1, INPUT);
  pinMode (IRSensor2, INPUT);
}

void loop() {
  int statusSensor1 = digitalRead (IRSensor1);
  int statusSensor2 = digitalRead (IRSensor2);
  if (statusSensor1 == 0){
    while (time< 20){
      servoJaw.write(jawlist[time]);
      delay(1000);
      time++ ;
      if (statusSensor2 == 1){
        break;
      }
    }
  }
}

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (nor for advice on) your project :wink: See About the Installation & Troubleshooting category.

Your description mentions one sensor, your code uses two sensors; maybe a better description is in place explaining the second sensor.

the main loop runs the code over and over again, right? i think it is breaking out of the loop, but just entering it again in the next cycle. this is the simplest fix i could think of.

#include <Servo.h>
Servo servoJaw; 
int servoPin1 = 3;
int IRSensor1 = 2;
int IRSensor2 = 7;
int time=0;
bool stopMotor = false;
int jawlist[] = {
  0,0,90,0,90,0,90,0,180,180,  //18
  0,90,0,90,0,180,180,0,90,180,  //28
};

void setup() {
  servoJaw.attach(servoPin1);
  pinMode (IRSensor1, INPUT);
  pinMode (IRSensor2, INPUT);
}

void loop() {
  int statusSensor1 = digitalRead (IRSensor1);
  int statusSensor2 = digitalRead (IRSensor2);
  if ((statusSensor1 == 0) && !stopMotor){
    while (time< 20){
      servoJaw.write(jawlist[time]);
      delay(1000);
      time++ ;
      if (statusSensor2 == 1){
         stopMotor = true;
         break;
      }
    }
  }
}

try to use second if, in out of the first if blocks.

Hello ale-xis

You might think about to replace the unpopular while() instruction by

if (time<20 && statusSensor2 == 1)

Revise the following processing part and pay attention to the limits of the time counter.
