If you like gambling, you should have this toy in your collection. Electronic dice (die) is very easy to build - it uses several component and quite few code lines.

Here you can find several Electronic die projects designed for different PIC microcontrollers by Pete Griffiths. These can be built on prototyping breadboard or as single application. Projects are ready for PIC16F84, PIC12F675, PIC16F690 and even on hard TTL logic.
