My reef pie is being a real pain, as it wont illuminate my led circuit from any of the pins I have configured. My circuit works when I hook straight to 3.3 or 5v but with nothing else. It is illuminating the LED on the relay board but will not engage the relay.
Can anyone advise on what I may be or may NOT be doing to cause this?
