Can I use my computer to close a circuit every second?
I posted this in the wrong place earlier. I have a counter which increases by 1 each time a circuit is closed. Is there any way I can use my PC to complete the circuit every second or so? I thought about using the parallel port but is there any way to not send voltage through into the circuit?

I suppose I don't really mind the mechanism but I thought that a parallel port would pass voltage into my circuit (which I definitely don't want). Basically, I have a counter that counts upward. I have two wires coming from the counter and each time the circuit is completed (wires cross), the counter goes up. I need it to go up around once a second is all :)

Yes, what do you need to press every second? Are you boosting mainichi issho? ;)

i would use a 555 timer circuit to do this task. it will leave your computer open for other tasks. you would use resistors to change the timings, but i am not sure what the values needed would be.

i would think that using a parralel port would be your first step....past that im clueless
