hello, I am trying to work out the circuit for a useless machine, I am sure many of you have seen these on youtube (mystery box) the ones they show are simple, and my wife would like one but only more advanced, first off she would like to have 2 flashing leds (easily done with a 555 timer and a few resistors and a capacitor or 2) second she would like not 1 but 4 arms so that a random arm pops out and turns the the box off, I know this would require a push button to do, the LED circuit has already been designed but I am not sure what ICs I need to randomize which arm pops out to turn things off can someone point me in the direction of a line of ICs that will work for this, bear in mind I dont have any programming skills or any programming boards available to use so if at all possible it will have to be purely un-programmed.
