Multi toggle button press?

multi toggle button

I'm trying to devise a way to implement connecting different pins using one button only. I'm trying to do this all in hardware with no programming involved. Programming it would be easy, but i was wondering if this is possible in hardware.

Ex:

button pressed zero times
led 1 - off
led 2 - off
led 3 - off

button pressed once
led 1 - on
led 2 - off
led 3 - off

button pressed twice
led 1 - off
led 2 - on
led 3 - off

button pressed three times
led 1 - off
led 2 - off
led 3 - on

And repeating like so with every button press.

Any ideas? I was looking into shift registers or possibly counters and a mux?

One of options is to use 4017 decade counter with 10 decoded outputs ..

Take a look at the attached 10-channel example ..
Re-configure 555 timer to button-operated-one-shot circuit (otherwise you will have to take care about button debounce problem) and to operate only 3 LEDs connect output [7] to [15] ..

It's relatively well known as a Johnson or Ring Counter and easy to do with discrete Flip-Flops. Here is an extensive explanation of how it works and you should be able to find a solution here:

Take a look at the 4017 and 4022 datasheets:
