Demonstration of a 4 bit register.
See entry 9 https://blog.jochumzen.com/p/entries.html 

Set the DIP switches 5-8 to any combination, say 0101.
Click the clock button to latch
The flip-flops "remembers" 0101
The LED Bars Q3-Q0 show the content of the flip-flops.
Change the DIP switches
The LED continuous to display 0101 until the clock again is clicked.

The component QuadDFlipFlop is also added. Its output is displayed on "Quad Q3-Q0"
It functions the same as the four D flip-flops.
