insert delay from serial...

Using Arduino Programming Questions

Hello guys.

I was needed to insert delay time for my other program I mean to pause it.

So I come up with this code... But I really don't like it.

So is there any other elegant way to write it. Thanks.

int emount = 0;
int delay1 = 0;
String Str;


 if(Serial.available()>0)
    {
    Str = Serial.readString();   
    emount = Str.length();

               if(emount == 1)
               {
                delay1 = Str[0] -48;
               }            
               
               if(emount == 2)
               {
                delay1 = (Str[0]-48) * 10 + Str[1]-48;
               }

               if(emount == 3)
               {
                delay1 = (Str[0] -48) * 100 + (Str[1] -48) *10 + (Str[2]-48);
               }

               if(emount == 4)
               {
                delay1 = (Str[0] -48) * 1000 + (Str[1] -48) *100 + (Str[2]-48)*10 +Str[3] -48 ;
               }
  
              if(emount == 5)
               {
                delay1 = (Str[0] -48) * 10000 + (Str[1] -48) *1000 + (Str[2]-48)*100 + (Str[3]-48)*10 + Str[4] -48 ;
               }

               
      Serial.println(delay1);
2 
 if(Serial.available()>0)
    {
    long delay1 = Serial.parseInt();
    Serial.println(delay1);
  }
3 
if(Serial.available()>0)
    {
    long delay1 = Serial.parseInt();
    Serial.println(delay1);
  }

For why johnwasser's code is better, in addition to being shorter, consider what happens in your code if the user types "Hello" instead of "10000".
