- Check if your arduino is actually on COM4 from Windows Device manager.
- Ensure you've selected correct arduino board in simulink hardware configuration
- Program your board using Arduino IDE to make sure your board is in working condition.
- Ensure your Arduino board is supported by the version of Simulink you're using.
- I don't believe there's any "Demo" port in simulink. Did you mean "Auto" ? If so, refer to step 1 above.
- Ensure the blocks used in your model are supported by Arduino board.
- Verify pin number for your Arduino board. THis always gets me as i work with several version of arduino boards.
Setup Arduino in Simulink port connection issue

I am trying to run the simple led tutorial but when I choose the correct port(COM4) it will not connect and I get a timeout error. The default port is DEMO and I don't get an error message and the program runs but it doesn't actually do anything in terms of communicating with the board. Any suggestions?
