These videos are a complement to my other instructable about Arduino_PID.

Now we have a FAN speed controller.

I hope you enjoy this project.

Cheers.

    Nice Instructable, thank you.

    What software are you using to monitor the PID performance?

    Hi you made a great job!!!

    I would like to ask you about puting the parametres of pid.Specifically, do you put them costantly? Or you have colculated ?

    "I try to find the mathematical model of this system and colculate the pid parametres."

    Thank you

    Hi,

    I did a pratical evaluation of the parameters.
    First I adopted a "P" value and after I increased the "I" value till get oscillation and then I decreased it in order to not have oscillation. I let the "D" value as zero.
