I am using the Shield Shield and Photon for a home automation project and have 2 PIR’s attached to D0 and D1 (A4 and A5 respectively on the Shield Shield). My live project is thinking the PIR’s are always being triggered even though they are not - due to 4.72 V being displayed on those pins - checked with my multimeter. When the PIR’s are triggered, the pins read 4.81 V, so they are seeing the event.
I was hoping these pins would be 0 and 4.8 V so the PIR’s would track motion properly (HIGH or LOW). Am I missing something here?
Will D0 and D1 always have 4.72 V across them?
Appreciate the help!
