From Instructables: explore:
Well, sometimes we need to switch something by position change or movement... It is easier than you thought!!!! I am going to cover 2 kinds of motion sensors in this instructable.
The first one is a ball-based movement detector . It detects any kind of movement. It's only disadvantage is that the contact time is really short at this sensor, so you have to connect it to a very sensitive circuit or prolong the signal length by a programmed PIC, somehow like Xyzzy did in his DIY RumblePak for Nintendo DS.
The second one is a position change sensor (well, it is ball-based, too). This is the sensor used in my other project, home-made Guitar Hero controller (will be uploaded soon). It is very simple and still quite effective!!!
