hi everyone:

Forgive my poor English :)

i first met Simulink these days.and i played all examples in it.

i want arduino can do things below in Simulink;i don't know how to setup up serial receive block.

can someone teach me a little bit :)

-------------------------------

              void setup() {                
                pinMode(13, OUTPUT);
                Serial.begin(115200);  
              }
              void loop() {  
                   while(Serial.available() )
                     if(Serial.read() == '1')    
                      digitalWrite(13, HIGH); 
                     if(Serial.read() == '2')    
                      digitalWrite(13, LOW); 
              }

Hi nt,

The easiest way to get to what you want is to add a Serial Receive block and add a comparator or a switch case block as you seem good for your logic at the output of the block to decide and then glow and LED.

I have attached a simple model snapshot that shows how to achieve a simple case !

Hope this helps

Thanks,
