Struggling getting arduino to do "2" thing at "once"

When it is done I will show you and explain it.

You will have to test the humidity thing. Because I don't have that sensor. I do have the temp sensor though.

Matthewdupreez · Aug 21, 2021

temp control, humidity control, and lcd monitoring are all good, it's just to incorporate the switches and servos (with the delay) into the code...

Matthewdupreez · Aug 21, 2021

this is the code that is working so far.....
at the moment it is just using a delay for the length of time the motor must run for....
prefeably it should monitor the leftsw and rightsw so that when one of those switches are pressed it will stop turning...

Yep. I am working on that now.

just checked and i think the while statement could work pretty easily.....

this might work? the ide says the code is fine... but it might not work properly irl

that whole while loop idea completely breaks your 'do 2+ things at once' initial request. Which is why you want to do some sort of FSM with changes

that is true... but if it only halts the system for about 2 seconds (time it take to rotate egg trays by 60 degrees, i don't think it would really harm the eggs....

obviously using an FSM would be the perfect solution... but right now my dad really wants his quail egg incubator to be working

FlamingRCAirplanes · Aug 21, 2021

Sorry that I have not been here. I have been redoing your code.

But over time that will build up.

???? what do you mean? it only turns every 2 hours

FlamingRCAirplanes · Aug 21, 2021

Going good so far.

Yes but over time that little delay will turn into a big delay... Like the turning time will become hours off.

hmmm... true....

Almost done!

cool.. can't wait to see what you have.

I got the delay working. It is using one arduino.
