This moduleconsists of a mercury switch, a 680 resistor and a LED that will light up when tilt is detected. The mercury ball will open/close the circuit when the module is rotated Mercury switch module and digital 13 interface comes with LED to build a simple circuit, the production of tilt lights with the digital 13 interfaces comes with the LED, the mercury tilt switch sensor access to digital 3 interfaces, when the mercury tilt switch sensor has a button signal, LED light, and vice versa. Connection Diagram: S : Pin 3 Middle: 5V – : GND
