problems with sketching the heart rate signal of AD8232

Hello:

Im using the AD8232 board distributed by sparkfun. It comes with a handy tutorial to test it:

https://learn.sparkfun.com/tutorials/ad8232-heart-rate-monitor-hookup-guide

I using software Processing to show the interface but the program still can't running. Anyone can help my problem?

Thanks in advance

Anyone can help my problem?

Probably not, because you did not say what the problem is.

The Processing sketch assumes that the Arduino is connected to the 3rd port in the list that Serial.list() returns. Mine is not. I have no particular reason to believe that yours is, either. Do you?

What Arduino do you have? What tutorials for the Arduino have you tried? What problem do you have?

So I must have change the code Serial.list() in processing Sir?
The code “println(Serial.list());” is error, what’s wrong with this code Sir?

he code "println(Serial.list());" is error, what's wrong with this code Sir?

What does this mean?

You should print something before and after the list, so you can see whether you have an empty list.
