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.


Instructions about the project:



The DC motor driver:



The reflective optical sensor:



Fan control in operation:
 

<p>once you have programmed, can be considered as a digital controller, isn&acute;t?</p>
<p>Nice Instructable, thank you.</p><p>What software are you using to monitor the PID performance?</p>
Hi you made a great job!!! <br> <br>I would like to ask you about puting the parametres of pid.Specifically, do you put them costantly? Or you have colculated ? <br> <br>&quot;I try to find the mathematical model of this system and colculate the pid parametres.&quot; <br> <br>Thank you <br>
Hi, <br> <br>I did a pratical evaluation of the parameters. <br>First I adopted a &quot;P&quot; value and after I increased the &quot;I&quot; value till get oscillation and then I decreased it in order to not have oscillation. I let the &quot;D&quot; value as zero. <br> <br> <br>Regards. <br>
