Description
With this electronic dice the result is displayed with LEDs that are
placed so every dice face is shown. In the circuit diagram, IC 4022 is
used to count to 6 in which only one output can get “1″ state.
A diode matrix (D1..D8) serve as decoding the output signals of the counter so that the LEDs are controlled by two buffer transistors and series resistance.

Integrated circuit outputs only support a reduced load, so in the
transistor’s base are connected the limiting resistances. As a clock
generator it can be used any generator with rectangular pulses whose
amplitude corresponds to the IC’s supply voltage. The 4022 clock input
impedance is 1012Ω.
