Let's say I have another micro controller board. It has a 2 pin header on it. If you momentarily connect those two pins together -- either shorting them out with a jumper cap, or hooking them up to a button and then pressing said button, and so on -- the board will reset.
Now let's say I want to set up my Arduino so that it can trigger this reset when a certain condition is met -- received a command over a wireless link, a counter passed a certain value, whatever.
How would I hook this up? What additional components would I need, if any? Do I just hook both pins of the reset header to Arduino pins and
digitalWrite(PIN, 1) them?
Sorry for this admittedly newbie-sounding question, but I am still fairly new to electronics.
