I'm looking for engnering know about Basic Electricity and have Mulitism to designe

Problem Statement:  Make a circuit that will nearly randomly display a "roll of the die" by lighting LEDs in a pattern similar to pips on a die. The user will press a push-button and when it is released the number (or "roll") will show on the LEDs. The randomness of the result should be dictated by the speed of the clock that is incrementing the counter. If fast enough the user cannot predict when to release the button to obtain a particular number -- so "sort of" random. Unpredictable, would be a better word. Use a state machine and not just the counter from the last lab, the state machine should use gray code. Include in your informal written report: design method, design steps, schematics, calculations, results, and suggested modifications if necessary.
