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.
