Strange effect

this code works fine:

Code:

void setup(){

 Serial.begin(115200);
}

void loop()
{
  if(Serial.available()>0) {
      char character = Serial.read();
      if(character=='1')
      {
        Serial.println("STATUS ON");
      }
      else if(character=='0')
      {
        Serial.println("STATUS OFF");
      } 
     
  }
}

this code does not work at all (added last else)

Code:

void setup(){

 Serial.begin(115200);
}


void loop()
{
  if(Serial.available()>0) {
      char character = Serial.read();
      if(character=='1')
      {
        Serial.println("STATUS ON");
      }
      else if(character=='0')
      {
        Serial.println("STATUS OFF");
      } 
      else Serial.println("UNKNOWN");
  }
}

Can anyone explain why?

Hi Boris,

Could you please try the code below?

Code:

void setup(){
 Serial.begin(115200);
}

void loop()
{
  if(Serial.available()>0) {
      char character = Serial.read();
      if(character=='1')
      {
        Serial.println("STATUS ON");
      }
      else if(character=='0')
      {
        Serial.println("STATUS OFF");
      } 
      else
      {
        Serial.println("UNKNOWN");
      } 
}

I can't try this right now, because I don't have my UDOO with me at the moment...

What did you mean by not work at all ? Compile but not run, not compile?
