I have almost no experience with electronics so this might be a stupid question.
I have a "switch" that I want to operate from a computer running Linux, it's actually two cables that I need to connect to each other closing the circuit for about 1 second. They operate at 5V.
I did some research and apparently I can do this with an Arduino, but since it seems like a very simple circuit I was wondering if I can build something with only a few components. I also found the Teensy board but it still seems overkill.
