I'm trying to simulate a button press on a PCB - potentially with Arduino and some additional components. I think I'll need to solder wires on either side of the button, connect those to an Arduino setup and toggle power on the wire maybe?
I've connected a multimeter set to 9 volt, and when connecting the leads to either side of the button I get a reading of -0.07. Does that give me an indication of the amount of power I need to pulse to the switch?
I may be approaching this the wrong way. Any guidance on what I need to be looking for is much appreciated.
Edit: When the button is depressed, the voltage goes to 0
