OK, so I am planning on building a really cool device with a bunch of switches on it, among other things. I am going to have a key switch (main power switch), several toggle switches with covers ("missile switches"), a 12 button keypad (for "authentication"), a character LCD with an RGB backlight, and a wave shield (so it talks/plays cool sound effects). I just don't know what to make these switches do...
I am just looking for general ideas, specifically creative ones.
