    Pardon my lack of knowledge.

    I am trying to design a simple circuit that consist of a push button, 2 led lights and a 3 volt battery.

    So far I manage to create a simple parallel circuit to light up the led however the lights does not remain on. I wish to toggle the led using one push button with the following result:

    1 push - Led1 light up
    2 push - Led 1 off, Led2 light up
    3 push - all off

    Possible to build the circuit with out any programming and what other components to I need? I hope some one can share with he their expertise on this probably via a diagram?

    Appreciate the assistance. Thank you!

    Yep use a Cd4013 dual flipflop, or Cd4017 counter.

    What you have described is a 2 bit shift register. Shift counters in an IC are usually 8 bit (but I think I remember seeing a 4 bit one that wouldn't be as over-kill). However, best way to do this would be to use a logic frequency divider like a D-type flip-flop.
