Being a rank amateur, customizing an off the shelf delay timer relay circuit is perplexing. It seems each circuit I purchase that is programmable has multiple programs, none of which meet my needs. My needs are:
Switch closes and stays closed
Timer starts counting down from 1 hour
If time goes to zero, relay closes
If switch opens before 1 hour, timer resets
I think that's all I need the circuit to do to start with. Eventually I would like to add the ability to send a text message if relay closes after 1 hour.
Right now I'm trying to learn to program Arduino but it doesn't seem my specs can be met by that system, at least so far in my study. Am I heading toward a dead end?
