I'm just wondering how I would go about getting the normal 5vdc that comes out of the Arduino analog/digital pins to a 0vdc signal? I wanting to mimic a push button (momentary switch) so that it acts as if I am pushing a button on a remote.
I'm sure I could use a resister of some value in order to get it down to 0vdc but I am unsure of that value nor am I sure that's the best way to go about doing something like this.
Any help would be great! Thanks!
Would using a TLP592A work doing it this way:
