Idea of Finite State Machine
Knob Puzzle The knob puzzle is consisted by basic diagrams such as square, triangle, circle, and star. When the piece of the puzzle is inserted in the right place, the user will get instant feedback from lights and sound. Also, the user will get finish feedback when he or she completes the puzzle.

Finite State Machine

A finite state machine (FSM) or finite state automaton (plural: automata) is a model of behavior composed of a finite number of states, transitions between those states, and actions. A state stores information about the past, i.e. it reflects the input changes from the system start to the present moment. reference : http://en.wikipedia.org/wiki/Finite_state_machine
