Hi,
I have a device (espresso machine) with a AC switch. I would like to know on my Arduino if the switch is open or closed.
What would be the best way to test this? I have direct access to the insides, of the machine and the leads to the switch. I can easily put something parallel or in line with the switch. But what?
Thanks!
