Project Name : Elaectronic playing Cube ( The Qube).

 

Project description:

This gadget will roll randomly a playing cube (the Qube)  and will display the result in leds arrangement.

The random number are seeded from a "electronic noise"  from analog pin of the Arduino. This to ensure real random number all the time. (Avoiding repeating sequence).

 

Components :

 Seven (7) leds to represent the rolled number.

Push Button - to start the roll.

A small red led at the lower left lit while the cube is rolling.
