How to put the data received by the serial port into a variable?

Pierre_processing

I have an arduino program that displays the value of a potetiometer, I can display it in the processing processing but I can not put the value of the data sent in a variable? I would do this so that the potentiometer can change the value of a slider controlp5

Thanks you

Here is the code, and I would like the speed knob to be managed by a potentiometer, and the data sent by bluetooth, have you tracks?
