Potential Divider using LDR

[electroblob]

I'm making a circuit for an automatic dusk/dawn curtain operator. I'll probably use a potential divider, but does anyone know how to apply that to an LDR?

Cheers

P.S. If anyone has any other ideas of how to make the circuit work, they would also be really useful. Thanks.

Same as you apply to standard resistors. Afterall LDR is also a resistor but a variable one.

Not sure what you're using , but ive built light sensor circuits using LDRs and comparators based on the circuits found on the page in the link below.
