    Hi guys, we have an ATC simulator with two digital clocks that need to have the same time displayed. We also need to be able to pause the clock via a single switch, ( to discuss certain things with the trainee) and then continue from the same position.

    Is there anyway to do this?

    Air Traffic Control would be my guess.

    Seems the easiest way to do this would be to use a single uC with a clock program and dual output drivers to control LED displays. That might be easier than LCD displays, as the latter require significant overhead in the way of housekeeping, etc.

    A single I/O pin might be polled for the start/stop function.

    Can you get into the clocks? If so, and there is a pause button function, you might be able to wire a pushbutton to act as a master pause control. You will need to be able to solder with some fine wire to do this - something like 26 ga stranded.

    If you can get them open, take some close-up pix of the outside showing controls and the opened inside. We can guess better that way.
