Servo control using DIP switch

I am pretty new to Arduino and programming too. I want to sweep a servo using DIP switch. At the moment, I use 4 position DIP switch. To each of the switches, I want to set the number of times the servo has to run. Eg., Pos 1 of DIP switch says, sweep for 5 times. Pos 2 says, sweeps for 10 times etc.

I wrote the following code:

#include <Servo.h>

Servo myservo;  
int pos = 0; 
int count = 0;   // might need later
int runXTimes = 0;

#define S1 2
#define S2 3
#define S3 4
#define S4 5

int s1state = HIGH;
int s2state = HIGH;
int s3state = HIGH;
int s4state = HIGH;


void setup() {
myservo.attach(9);
pinMode(S1, INPUT_PULLUP);
pinMode(S2, INPUT_PULLUP);
pinMode(S3, INPUT_PULLUP);
pinMode(S4, INPUT_PULLUP);
pinMode(9, OUTPUT);
}

void loop() {

s1state = digitalRead(S1);
s2state = digitalRead(S2);
s3state = digitalRead(S3);
s4state = digitalRead(S4);


// Servo control through Switch 1
if (s1state == LOW) {     // read the input pin
for (int runXTimes = 0; runXTimes < 5; runXTimes++) {    // Servo to     sweep for 5 times
for (pos = 0; pos <= 80; pos += 1)  // goes from 0 degrees to 80 degrees in steps of  degree

{                                   
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
  delay(5);
}

for(pos = 80; pos>=0; pos-=1)     // goes from 80 degrees to 0 degrees
{                               
   myservo.write(pos);              // tell servo to go to position in variable 'pos'
 delay(5);
}
          
}

}

 // Servo control through Switch 2. Used servo detach here
 else if (s2state == LOW) {  // read the input pin
 for (int runXTimes = 0; runXTimes < 10; runXTimes++) {  // Servo to sweep for 10 times
 for (pos = 0; pos <= 80; pos += 1)  // goes from 0 degrees to 80 degrees in steps of  degree
 {                                  
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
 delay(5); 
 }

 for(pos = 80; pos>=0; pos-=1)     // goes from 80 degrees to 0 degrees
 {                               
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
  delay(5);  
  }
  
  }
  myservo.detach();
  }

 // Servo control through Switch 3
  else if (s3state == LOW) {  // read the input pin
  for (pos = 0; pos <= 80; pos += 1)  // goes from 0 degrees to 80 degrees in steps of  degree
  {                                  // 
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
  delay(5); 
  }

  for(pos = 80; pos>=0; pos-=1)     // goes from 80 degrees to 0 degrees
  {                               
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
  delay(5);  
  }
  }

// Servo control through Switch 4
  else if (s4state == LOW) {  // read the input pin
  for (pos = 0; pos <= 80; pos += 1)  // goes from 0 degrees to 80 degrees  in steps of  degree
  {                                 
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
                     
  delay(5); 
  }

  for(pos = 80; pos>=0; pos-=1)     // goes from 80 degrees to 0 degrees
  {                               
  myservo.write(pos);              // tell servo to go to position in variable 'pos'
  delay(5);  
  }

  }
  }

The actions that happen with the above code are:

  1. Servo control through Switch 1 - If I switch ON (0) and then OFF (1) immediately, the servo sweeps for 5 times. Works more like a button switch. If I switch ON and OFF (immediately) again, I am able to sweep 5 times again. But, if I leave the switch in 1, the sweep does not stop after 5 times.
  2. Servo control through Switch 2: If I switch ON, the servo sweeps for 10 times and stops as per my interest. But, if I change the switch to 0 and 1 again, the sequence does not start. In fact, no other switch works. I need to power OFF the Arduino to run the program again.
  3. Servo control through Switch 3 (= switch 4): If my switch is 1, the servo sweeps. If my switch is 0, the servo stops.

Could you please suggest:

  1. How to write the code so that my servo sweeps only for the set number of times even when the switch is in 1 always or whenever I toggle between 0 and 1?
  2. I do not want to use serial communication (or typically a PC). Is it possible to interface a 7-segment or LCD to display the number of sweeps completed or still left.

Thank you in advance.
