A method and apparatus for illuminating lighting elements in one or more
predetermined patterns. A preferred frequency controlled lighting system
implementing this method includes a motion switch, a controller, a sound
generator, and lighting elements. The motion switch creates an activation
signal in response to movement of the motion switch, which is detected by
the controller. In response to the properties of the activation signal,
the controller illuminates the lighting elements in one or more
predetermined patterns, or the controller actuates the sound generator to
generate sound. Preferably, the lighting system utilizes at least two
integrated circuits where a first integrated circuit functions as the
controller and a second integrated circuit, having a higher cutoff
operating voltage than the first integrated circuit, functions as the
sound generator.
