Random Selecting Output

Not open for further replies.

I am trying to make a toy and I want to make a circuit that outputs one of 9 LEDs at random. Once an LED is selected at random you can press a switch next to that LED (Each LED has a switch joined with them). When you press the switch joined to that LED, that LED switches off and another LED switches on at random, and it carries on in the same way. Please Help Me!! I have drawn up a circuit (as an attachment) that works with 2 LEDs but as you can see it is not very exciting and this circuit isn't random selecting.
