I went into one of the toilets in a mall. Saw the auto flushing and couldn't stop thinking about it. So here it is.
This model illustrates auto flushing in the men’s toilet (or women's). When it detects human presence, it will flush once before peeing begins. When the process is completed, it will flush again. Flushing is represented by a rotating DC motor.

I did not work with s-functions at all , where to start (any recommended readings,videos,course)?

I get error: 'sonar' undeclared (first use in this function)
int uS = sonar.ping_median();

What am I doing wrong?

Hi Ihab, yes it is possible to run the S-Function on the Arduino UNO.

Do i need to specify data in the model explorer for the chart?
