Hello,

There are a lot of schematics to find on the internet.
Here are some examples:

The second one is for 120 Volt, but with another tranformer it will work for 230 Volt too.

In Mustafa's circuit (first link provided by Bertus) I suggest using comparators instead of LM324 Op Amps. Op Amps will wear out sooner when used as comparators.
