Power switch again, but without mechanical switch
farblos 2020-01-23 22:58:05 4071 Views3 Replies I've been browsing the posts related to powering alpha/delta remotely using attached switches. However, all the discussed switches were mechanical ones (counting a relais as mechanical switch).
Is there an option to connect the LP SW pin directly to a digital pin of the Arduino? Like: Put Arduino pin into high-impedance mode => SW not pressed, drive the Arduino pin to low => SW pressed.
If decoupling is required, how about some optocoupler logic? Using a relay seems so 20-century-ish.
Thanks.
