First of all thanks to all the forum members that helped me with my light detector circuit, it now works great.
I now would appreciate some help with my darkness detector. The attached circuit is very similar to my light detector except I swopped the inverting and non-inverting connections around. Is this OK?
The circuit runs off a standard 9V battery. I measured the output at pin 1. When the LDR is in light, pin 1 is at 6.4V. When the LDR is in the Dark the voltage at pin 1 drops to 1.8V.
Would it be possible to connect my camera (DSLR)to pin 1 so that when the LDR detects darkness the camera is activated? I suppose I could use a relay but would prefer some sort of an optoisolater so that there is less chance of the camera being damaged in any way.
Once again your help will be appreciated.- JDR04
