I’m trying to wire my photon to the relay here: http://www.amazon.com/SunFounder-Channel-Shield-Arduino-Raspberry/dp/B00E0NTPP4/ref=sr_1_1?ie=UTF8&qid=1445489474&sr=8-1&keywords=sunfounder+relay
-I wired the VIN to jv-vcc (took the jumper out first)
-Wired 3V3 to VCC
-Wired GND to GND
-Wired D0 to IN1
When I do digitalWrite(HIGH), the led for IN1 turns off. When I do digialWrite(LOW), the led for IN1 turns on. Since this module is inverse logic I’m assuming that’s how it’s supposed to be.
The problem is the relay isn’t closing/opening at all. I ran power to the COM line and hooked up a light to the NO(Normally Open) and the light just stays on. It never turns off.
My question is did I wire something here or is this just a bad relay module?
