ABSTRACT:
An electronic random selection device includes integrated circuits connected to receive a signal from a power source, to generate a first oscillating signal when an associated switch is in a first position and to generate a second oscillating signal, slower than the first oscillating signal, when the switch is in a second position. A plurality of light emitting diodes are sequentially illuminated by the first and second oscillating signals and due to the effect of an interconnected time delay circuit, when the switch is in the second position, the second oscillating signal is ultimately induced to illuminate only one of the diodes. The selection device can be applied to an amusement display such as a playing board having a predetermined array of light penetrable openings formed therein and the light emitting diodes positioned adjacent the openings.
