ABSTRACT:
An amusement device (10) to produce an audio output from an audio transducer (76), as well as a visual output from a plurality of light emitting diode elements (68, 70, 72, 74). The light emitting diode elements (68, 70, 72, 74) are intermittently lighted in accordance with a predetermined first frequency determined by a first photoresistor element (52). The first photoresistor element (52) includes a circuit coupled to a first oscillator circuit (20) which determines the first predetermined frequency of the visual output system (66) responsive to the amount of photons impinging on first photoresistor element (52). Correspondingly, a second predetermined frequency for audio transducer (76) is determined by second photoresistor element (82) which is coupled to a second oscillator circuit (22) for producing the predetermined second frequency. A coupling line 96 is utilized between an output terminal (62) of the oscillator (20) and a reset terminal (94) of the second oscillator circuit (22) for providing a synchronous visual and audio output.
