Recently I've been working on a zero crossing detector circuit for audio modulating a flyback transformer.
So far it's working great, but I have a few questions regarding the circuit and its operation.

Well my question is:
What is the purpose of R2, R3, and R5 in the zero crossing detector section?
What is the purpose of R2, R3, and R5 in the zero crossing detector section?Is it possible to use the zero crossing detector circuit at a lower voltage level, for example 5 V supply, and what components must be changed?

My question might be elementary but your answers will be very helpful and useful for me.
