How to make Arduino runs continuous routines even inside a "switch case loop".

AWOL:
Program structure is easier to follow if you indent it like this

void loop()

{
 if(Serial.available()){
   ch=Serial.read();
 }



or

void loop()
{
 if(Serial.available())
 {
   ch=Serial.read();
 }




The compiler doesn't care, but my first reading of your revised code was that nothing had changed.

Looking at my first post you can observe what I wrote is:

void loop(){
  if(Serial.available()){
    delay(100);
    char ch=Serial.read();
    switch(ch)
    { 
      case '1':
      SHT1();
      break;
    .......
}

Now I've changed the code:

char ch=0;

void setup(){
....}

void loop(){
  if(Serial.available()){
    ch=Serial.read(); 
    }
    switch(ch)
    { 
      case '1':
      SHT1();
      break;
      ......
      }
      }

This is pretty different! Anyway my own Arduino now works exactly as I wish!!
