My relay keeps clicking when I reset my Core. Its activated by a low signal.
I had assumed the IO pins, (ie D1), would be in tristate, (neither ground nor positive), but it seems, the IO pins go to ground, and can sink a good bit of current. I tested amps and stopped when I got up to 8.7 ma.
If the Core does this, am I to assume that the Photon will also?
