Hi! How can I use one of the arduino nano outputs as a simple push button. My first idea is to control a relay with aurdino. However, my question is, is there a simpler solution for digital components?
Thx
Probably yes, but it all depends on the circuit. So a relay is the most drop in replacement if you don't know the specs.
you can just attach a button instead of the arduino if you want to push a button and turn on a relay.
Depends on the circuit you want to control.
An optocoupler can be used if voltage/current is low.

In short the XY problem.
Start by explaining what you actually want to do.
