Analog input and time series vizualiser issue

hi, i´m new using Bonsai, i´m trying to see the data of a potenciometer with the "time series vizualiser", I already upload the "standar firmata" in my arduino Uno board, I also followed the steps from the Exercise 6: Saving analog data of the Bonsai Tutorial, but the csv file doesn´t shows nothing and neither the vizualiser. I´m using the pin A0 of the analog input in my arduino uno.

I also veryfied the correct function of the standar firmata with a firmata test and it works well, can someone help me to see and save the data?

I use the potenciometer just for test because after that I want to use an phototransistor to use in an operant chamber for some experiments with rats as a nose poke sensor.

Also I have the trouble that when I stop the workflow and try to run it again, a message that say "the acces to com port X has been denied" appear
I have to unplug the usb cable and reconenct it every time I stop the workflow, can someone help me to fix that too?

The digital output node in Bonsai Works well, I can turn on and off the led of pin 13

tecnical considerations:
I use Windows 11
Bonsai 2.9
Arduino package 2.9
Standard firmata

thaks for your time

@Garlex15 just to confirm, you are using the Arduino Uno R3 right?

Sorry, I think the tutorial is missing a step, can you initialize the connection to the Arduino first, by using the CreateArduino operator. You can give the connection a name like MyArduino and then configure the PortName property for AnalogInput to target MyArduino.

Hi @banchan86, yes, I´m using the Arduino Uno R3

I tried like that and still the same, no signal in the visualizer.

Another thing that I can do for it?
