I know almost nothing about this stuff but have a task I would like to accomplish, but I need help!
I would like to build as simple a circuit as possible that allows a relay coil to be energized after a trigger, but only at night (reasonably close to dusk/daylight is plenty good enough). Here's what I have at the moment: after a trigger, a 3.6 volt signal will be available from another electronics board. On the other end, I will have a normally open relay wired to some other device and would like the voltage to be passed to the relay only at night. I was thinking that a photocell would be one way to do this, but can't seem to find what I need to do. Basically, I just want the circuit to be completed at night (allow the 3.6V to close the relay), but not in the day.
Can anyone help? Sorry if this is a really dumb question.
