Dim lights on overheat?

I would like to dim the lights on overheat (instead of using a port for my lights).

Can someone point me in the right direction?

Thanks,

Are you using LEDs? Standard dimming ports or expansion? What temp to trigger the overheat? What value to dim to when there is an overheat?

LED's, standard ports, 83 degrees F, and dim daylight and actinic to 20% (possibly to 0).

Thanks,

Do you want it to be a true overheat flag or just > 83 for a temp probe? If just the temp probe which probe number?

Hmmm, I would rather the lights came back on when the temp came down, so how about lights dim to 15% at T1 >= 83 degrees, and come back up at T1 <= 80?

Thanks,

Try this:

Code: Select all

static boolean overheat=false;
if (ReefAngel.Params.Temp[T1_PROBE]>=830) overheat=true;
if (ReefAngel.Params.Temp[T1_PROBE]<=800) overheat=false;
if (overheat)
{
  ReefAngel.PWM.SetActinic(15);
  ReefAngel.PWM.SetDaylight(15);
}

Just make sure to place it after your PWM functions and before ShowInterface().

No problem. Now, if I only hadn't blown out my dimmer circuit. Cracked the op-amp right down the middle. :(

Sweetness. Hopefully that's all that got damaged on the voltage 20 car pile up lol.

So part came in, replaced it, and all is well.

If anyone needs a LM358, I ordered some extra. :D

Lol. I ALWAYS need more components! Hahaha.
