1. An electronic random selection device comprising in combination:

  • a control switch having first and second selectable positions;

    first integrated timer circuit means connected for generating a signal oscillating at a first constant rate when the control switch is in the first position;

    resistance means connected for causing the first timer circuit means to generate a signal oscillating at a second constant rate, slower than the first rate, when the control switch is in the second position;

    second integrated timer circuit means connected for generating a time delay signal to the first timer circuit means when the control switch is in the second position;

    integrated decade counter circuit means connected to the first timer circuit means for receiving a signal therefrom and for generating a binary coded decimal count;

    integrated decoder/driver circuit means connected to the decade counter circuit means for receiving a signal therefrom and for decoding the signal to a decimal equivalent signal thereof; and

    a plurality of light emitting diode means connected to the decoder/driver circuit means for receiving the signal oscillating at the first rate for sequentially illuminating the diodes at a rate corresponding to the first rate when the switch is in the first position, for receiving the signal oscillating at the second rate for sequentially illuminating the diodes at a rate corresponding to the second rate when the switch is in the second position and for receiving the time delay signal for ultimately illuminating only one of the diodes when the switch is in the second position.
