    Hello World!!
    I am working on Ping Pong Led state Machine project and using 2 or 3 74LS74 Dual D positive edge Flip Flops.
    2 74LS194 4-bit bidirectional shift register, serial/parallel in, parallel out, asynchronous clear, load/hold/left/right Some Other logic gates
    8 + num-state-bits LEDs and current-limiting resistors.
    The circuit is easy but the thing which is bugging me is that how can i add more feature or best approach.
    How can i add more option in a simple ping pong state machine and according to you geniuses what will be the best approach
    Thanks in advance :)

    There is a reason why 48 people have viewed your post and yet none has responded. Your question is terrible. For example, it assumes that everyone knows what a ping pong state machine is. I don't. Do you?

    Also, nice schematic.
