Hello there. I’m working with a Photon and a Shield Shield. I would like to use a couple inputs to monitor dry contacts. In my code I set the inputs, D2 and D3, as INPUT_PULLDOWN. If I have the the Photon mounted in a breadboard, the inputs seem to react as expected - LOW when not connected to anything and HI when connected to 3.3v. When I mount the Photon in the Shield Shield and have it running the same program, the inputs act differently. They act as if they have no pull up or down at all. If I connect 3.3 to the input, it shows HI. When I disconnect 3.3, it stays HI until I connect the input to GND. I have tried setting the input to PULLUP and it acts the same. Is this behavior possibly caused by the voltage translators?
I know the inputs are mapped to 11 and 12 on the Shield Shield.
Thanks in advance!
