Arduino send data to duet



  • I'm using an arduino with thermistors attached to control fan speed for one of the fans cooling electronics. There are a couple of things I'd like to do:

    1. report 1-4 temperatures back to the duet that'd be viewable in the extra tab

    2. report if the fan is spinning to stall M81 S1

    I'm using a duet maestro and have a paneldue attached w/ 4 wire cable (it seems like the general advice is to talk to arduino with the paneldue port)



  • Also, if I could connect 3 more thermistors and another relay that would negate the above question. I have e0temp available but I don't think there's anywhere for the other 3 thermistors or the relay for the fan.



  • @jphilly said in Arduino send data to duet:

    report 1-4 temperatures back to the duet that'd be viewable in the extra tab

    If you have unused Duet analog temperature sensor inputs, theoretically you could use digital resistors controlled by the arduino to feed the temperature at some accuracy level into the duet.

    (or a servo attached to a mechanical potentiometer).



  • @zapta I just want to turn the fan off and on so assuming my relay works with a 3.3v expansion pin that's good, thanks.
