In reply to Golam Rasul Chowdhury. Try changing the value of R1, such that it will reduce the effect of LDR resistance. You can also provide a positive feedback for the opamp (schmitt trigger).

Good Evening…

Sorry for disturbing you again. I’m only a beginner in circuit designing.
Can I ask one more thing?
I want to design a circuit that uses XNOR ic but I cannot make one even simple one.
Can you make schematic circuit design that uses XNOR ic’s for me?
I know it is to much.

I hope you can help me.
