Programmable electronics dice project


Dice game is very interesting indoor game mostly played in childhood. Here is verified game project programmable electronics dice useful in many game.  With the help of this project we can display any number between 1 to 9 according to our dip switch setting.

Circuit description of programmable electronics dice

The project programmable electronics dice comprises three ICs as heart and for output a common anode display. Here, IC1 used is a dual 4-input Schmitt trigger NAND gate IC where gate N1 used as frequency generator which generate the clock frequency of 70kHz with the help of resistor R2 and capacitor C1 and gate N2 load data at the input of IC2. Where IC2 is a presettable binary counter with the facilities of parallel loading. Lastly the output of IC2 is displayed on common-anode, 7-segmant display with the help of IC3 which is BCD-to-7-segmant decoder and the resistor R8 is used as current limiter.
