1. An optical controller comprising:

  • a plurality of lights, wherein each of said plurality of lights transmits a different color;

    a processor coupled to said plurality of lights, wherein said processor sequentially pulses each light of said plurality of lights in a predetermined light sequence;

    a user response sensor coupled to said processor, said user response sensor having a first state of operation and a second state of operation;

    a memory coupled to said processor, wherein for each light of said plurality of lights pulsed by said processor, said processor registers said state of operation of said user response sensor in said memory as a user response; and

    a comparator circuit coupled to said processor, wherein for each light of said plurality of lights pulsed by said processor, said comparator circuit compares said user response to a predefined response, wherein said comparator circuit outputs a first signal if said user response does not match said predefined response for each light of said plurality of lights, and wherein said comparator circuit outputs a second signal if a predefined plurality of user responses match a predefined response sequence.
