Thanks a lot!!!
now it works!!! the BPM values are seen from vvvv.
the only problem it’s that I must click with the muose every time I want to send data.
I’d like that data was sent automatically every 2 or 3 second, without clicking the mouse button.
there is another function to do that automatically or I must do it manually only with “mousePressed”?

thanks to you, too. I have alredy used the node RS232. I have another sensor, of temperature. in this case I don’t use processing because I have in the serial monitor the value ready to be used from vvvv thanks to the node RS232.
But in the case of the pulse sensor I need that arduino continue to send to the serial monitor the data to turn on and off the LEDs, and not the BPM value.
