Howto "press" a physical button on a coffee machine
Posted: Sat May 09, 2020 7:34 amHi,
I have a pretty candid question: I'm looking into the easiest way to remotely trigger a physical button on a coffee maker.
My idea, so far is to: piggyback on the physical button on the machine, and, using an ESP8266 and its gpio to use that button.
My question is: will it send a current ? What is needed is simply to "close" the circuit, not to send any power as when ie turning on a led.
The digitalWrite function seems to be able to do that, but I'm not really confident this is the right way to go
Thank you !!
Update> I arrived to the conclusion that a relay was better suited, so I purchased an esp8266 + a relay module for this
