I have a coffee machine that has one button. When this button is pressed, the coffee machine will do its thing and automatically shut off after a certain period of time.
I need to use a signal from an Arduino paired with a relay to turn this coffee machine on automatically. I don't have too much experience doing things like this so I need some advice. My instinct is to short out the button in the machine and just turn it on/off with the relay. Would this make sense?
Obviously since coffee machines differ, I'm not asking for the exact process. I would like some advice as to how I would go about doing this on any coffee machine (what to look for, etc). Also, I'd like to know what my other options are.
