Hi, I want to realize a circuit, connected to analog/digital input of arduino, that put arduino output to high if a lamp (powered with 220vac) became broken (even if 220vac is present. Can anybody help me? Thanks.

Not really good for anything, but they bring a smile to your face when pushed down the stairs.

What about an ldr? That would test the most important thing: "is the lamp generating light?"

If that would work, you don't need an Arduino. An analog comparator would work, and they don't need any code.
