Hello
I have to work with some old circuits that use some underground wiring to another circuit bleh blah.... in short terms. I have to accept that 230v is what I am supplied with as an input signal for my circuit, a signal that is switched on when a car drives by some old laser beam things.
Only the signal for an input pin that is. My circuit runs on its own supply.
How can I do this?
Would a trafo 230v to 5 v and acdc converter be the way to go?
Thanks in advance
