Yeah, my LED-based light (named for a Greek god) is great, but below 1V, the LEDs just shut down since the driver can't go lower. As I was watching the cloud-dimming simulation—something that I really do enjoy, thank you Roberto et al—I just thought it would look smoother in my application to stop t...

I'm unsure entirely if this has been covered, but is there a way to define how much the daylights dim during cloud cover? In other words, instead of dimming all the way down to 0V, dim down to 1V (or 10%, however you look at it)? If so, how? It would be kind of cool if the dimming amount was random,...

Much appreciated to both of you!

I'd like to ask either of you for your final code where you got the times to line up. I'm just not comprehending exactly what values to change, and how they interrelate to get the time and duration to overlap over the zeroes. Hopefully, by seeing what you've done, I can monkey-see, monkey-do my own ...

It worked as expected. The pump turned off after the elapsed time, and it stays off until the unit is powered off and back on. This is no problem since this "feature" is something I hope won't be needed in the first place, but will be there in case. Like right now as I'm trying dial in my ...

Excellent. I'm out the door to work, but I'll try when I return from work and will let you know.

Thanks, sir.

Yeah, that's the gulf in our understanding. My sump is pretty small, and the return section will get low enough that the pump will create an air vortex when the water level is within a few inches of the pump. It only takes 12 hours from one ATO cycle to the next, and maybe another few until the pump...

The ATO pump, yes, would shut off at the defined period, but that's not what I'm hoping to do here. I'm wanting to use the lower float to shut off the return pump after a defined period where the lower float is in the down position, irregardless of what is going on with the ATO. Is this just somethi...

I am using the StandardATO setup. I'm just thinking that there may be cases where for whatever reason the ATO timeout would trip because there wasn't enough time to get the upper float in the up position, but the lower float would be in the up position. In that case, it would be fine in my setup for...

I'd like to use my lower (of the dual float setup) ATO float switch to shut off my return pump on port 8 when the float is in the lowered position for more than 5 minutes. I think I'd prefer it stay off until cleared out manually. This would take care of cases where the ATO pump has died or the skim...
