    Hi All,

    This is probably going to be an awkward start, but I am trying to post up a project I made some years ago. The hope is that it will illustrate some uses of digital logic.

    I haven't got all the parts together, but am going to post the first two "installments" to begin with. The idea is to state why things were done and to respond to questions. You'll have to bear with me, as the forrest is going to be built up a couple of tree at a time.

    This post covers the logic for the count-down timer and the control logic in the buzzer system. More to come...
