Hello world! Today i made a example on what you could to with the Mercury Switch. Also known as the Magic Light cup in the arduino world (still not sure why they call it that) Anyways it is a mercury switch with Leds attached to it, nothing more. This example shows you how to make a tilt alarm. When you tilt left or right the Lamps will flash.
