Component Introduction 
The  tilt  sensor  is  a component  that  can  detect  the  tilting  of  an  object.  However  it   
works like a normal switch but  through a  different physical mechanism. This type of 
sensor is the environmental-friendly version of a mercury-switch. It contains a metallic 
ball inside that will conduct the two pins on and off when the sensor reaches a certain 
angle and vice versa.
