2 hour multpile timers help?

Hi there,

I’m slightly stuck, I need to time 4 inputs and when one is not pulled down for over 2 hours (7200000micros) I need the corresponding output to switch on.

The problem is that I don’t know how to have several timers (let alone one) running waiting for nothing. And then restarted if the inputs are pulled down?

You mean millis, not micros.

The demo several things at a time should give you some ideas. You just need much longer intervals.

While you are developing your project use short intervals and only go to the full 2 hours for final tests.
