Dark detector using LDR and IC 555

[Anuj Shayan]

Hello,

I want to make a circuit work in dark using a LDR and IC 555. I googled for this and got my circuit diagrams, but they contain an additional battery but my circuit has an in-built battery also, so i am not in need of a power source in the circuit. So can i get a circuit diagram for my circuit to work in dark?

Thank you!
