How to create dice circuit

Want to create a random digital dice.

What other IC other than a 4017 can one use for a decade counter?

I have a 555 timer abstable mode

Perhaps, JK flip flops or any other IC?

Thanks

Hi,

Are you into microcontrollers?
If so you can make two dice with one chip.

Other than that, there are a lot of ways to do this.
Gang flip flops to make a binary counter for example that resets after 5, or start from 1 and reset after 6.

What do you intend to use as display, 6 LED's ?

No microcontrollers
Only 555 timer, jk ff , and bunch of LEDs

Hi,

Then you have to learn how to gang the JK flip flops into a binary counter.

Next, and this is important too, do you want to display the results on six LED's numbered 1 through 6 or do you want to arrange the LED's in the form of the dots you see on a real life die? Look at soime pics of dice and see if you can figure out a way to arrange them so that you can light them up to look like a die after it stops rolling. It will be a little tricky.

Either way you will also need a 1 of 8 decoder chip. That will decode the 6 states into 6 exclusive outputs that you can use to drive the LED's. Some LED's may turn on for different states (for the real life look alike die) so you may need OR gates or NOR gates or diodes actinig as OR gates.

Make sense so far?

Are you looking to design this yourself or you looking for a ready made circuit?
What exactly is your assignment, to design one, just build one, or both design and build one?
