So yeah, another one. In this part of the Bomb game I would need some kind of chip that will randomise between 1-4 outputs. So when you start the game it it would an output between 1-4 and this could be 3. At this point, wire 3 would be powering the countdown and speaker logic areas and to stop it you would have to pull out wire 3 to Defuse the bomb.

P.S expect more bomb game posts.
Thanks

 

Look at PICs and AVRs

Have a two bit counter clocked at a few Khz by a free running oscillator. Also have a two bit latch connected to is and use a trigger such as the start of the game to clock the state of the free running counter into the two bit latch. This should give faily random count of 0 to 3 which could be displayed to the user as 1 to 4.

Sorry for the really late reply, but I was originally going to use no arduinos.
