Adding pause to servo sweep

Projects General Guidance
1

Hi
Im new to the forum.

I have found a sketch that is exactlly what I want for my project, but I want to modify it.

The sketch does the following: the push-button is pushed once, the servo goes from 0 to 180 degrees and back to 0.
I want to add a pause when the servoe reaches 180. So it goes from 0 to 180, pauses for X seconds, and goes back to 0 without further input.
I have tried adding the delay-function into the code I have but I cant seem to find the right place.

Would delay(5000); be the proper function to use?

My question is: where do I supplement the code that I have with the proper function to make it pause at 180 degrees?

Here is the code:

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
#define servoPin 3 //~
#define pushButtonPin 2 

int angle =90;    // initial angle  for servo (beteen 1 and 179)
int angleStep =10;
const int minAngle = 0;
const int maxAngle = 180;

const int type =2;//watch video for details. Link is at the top of this code (robojax)

int buttonPushed =0;

void setup() {
  // Servo button demo by Robojax.com
  Serial.begin(9600);          //  setup serial
  myservo.attach(servoPin);  // attaches the servo on pin 3 to the servo object
  pinMode(pushButtonPin,INPUT_PULLUP);
   Serial.println("Robojax Servo Button ");
   myservo.write(angle);//initial position
}

void loop() {
  if(digitalRead(pushButtonPin) == LOW){
    buttonPushed = 1;
  }
   if( buttonPushed ){
  // change the angle for next time through the loop:
  angle = angle + angleStep;

    // reverse the direction of the moving at the ends of the angle:
    if (angle >= maxAngle) {
      angleStep = -angleStep;
        if(type ==1)
        {
            buttonPushed =0;                   
        }
    }
    
    if (angle <= minAngle) {
      angleStep = -angleStep;
       if(type ==2)
        {
            buttonPushed =0;       
        }
    }
    
    myservo.write(angle); // move the servo to desired angle
      Serial.print("Moved to: ");
      Serial.print(angle);   // print the angle
      Serial.println(" degree");    
  delay(100); // waits for the servo to get there
   }

  
}

The code is from Youtube: Control Servo motor with a Push Button: Move Servo and Return SPB-1 - Robojax
I know that I dont need the serial.print stuff, but hey...

All response highly appreciated. Thanks.

Try this, dirty but but maybe working. Look for "Railroader" in the code.

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
#define servoPin 3 //~
#define pushButtonPin 2

int angle = 90;   // initial angle  for servo (beteen 1 and 179)
int angleStep = 10;
const int minAngle = 0;
const int maxAngle = 180;

const int type = 2; //watch video for details. Link is at the top of this code (robojax)

int buttonPushed = 0;

void setup() {
  // Servo button demo by Robojax.com
  Serial.begin(9600);          //  setup serial
  myservo.attach(servoPin);  // attaches the servo on pin 3 to the servo object
  pinMode(pushButtonPin, INPUT_PULLUP);
  Serial.println("Robojax Servo Button ");
  myservo.write(angle);//initial position
}

void loop() {
  if (digitalRead(pushButtonPin) == LOW) {
    buttonPushed = 1;
  }
  if ( buttonPushed ) {
    // change the angle for next time through the loop:
    angle = angle + angleStep;

    // reverse the direction of the moving at the ends of the angle:
    if (angle >= maxAngle) {
      delaye(5000);//                               added by Railroader
      angleStep = -angleStep;
      if (type == 1)
      {
        buttonPushed = 0;
      }
    }

    if (angle <= minAngle) {
      angleStep = -angleStep;
      if (type == 2)
      {
        buttonPushed = 0;
      }
    }

    myservo.write(angle); // move the servo to desired angle
    Serial.print("Moved to: ");
    Serial.print(angle);   // print the angle
    Serial.println(" degree");
    delay(100); // waits for the servo to get there
  }


}

or you can just put a delay inbetween the 2 for loops...

Where can you see any for loops in the code from the original post that you're replying to?

Yes, if 'X' is equal to 5.

Right after:

    // reverse the direction of the moving at the ends of the angle:
    if (angle >= maxAngle) {

Thanks guys!
It works as intended!
Awesome.

Thanks for telling! Well done!
