hey gang, does anyone know if it's possible to use mains AC as a switch for the 'duino?
A little background:
Calculon is working on a project that he hopes will take advantage of his doorbell's AC power. He wants the old-school analog doorbell switch to activate a function on his arduino instead of firing off a solenoid in the door chime. Is this possible with some sort of voltage divider? He doesn't need to measure the current, voltage, phase, or anything liek that, he just needs to sense on/off like a pushbutton. He assumes the initial doorbell voltage will be 120V.

Pulling a rabbit out of a hat is a neat trick. But how about wowing crowds of kids with an old suitcase that performs magic thanks to 18 synchronized, Arduino-powererd servos that whir about hidden from view?
In many respects Mario "the Magician" Marchese, with his narrow suspenders and pork pie hat, is an old-school magician. He performs on the sidewalks of New York City with with nothing but the power of his voice and a bag full of tricks that looks like old timey, slapstick gags — epaulets that unexpectedly pop up in the air, banners that "accidentally" fall behind him, and spinning ribbons on his lapel.
