Connect a 4 bit counter (e.g. Counter-4 Min) to the hexadecimal digit display (e.g. Hex Display). Connect the Binary Switch to the clock input and change its state (0-> 1 -> 0 ) several times, i.e. generate a sequence of pulses, to step the counter through all 16 states. Capture the screen with the display showing hexadecimal A. You may test your counter with the Clock component connected to its clock input to make it count the clock pulses generated automatically. The clock frequency can be adjusted in Logic Works menus.
