I built a circuit accordingly and as shown in the second image:

The instructions at the end say I need to use 7400 chips.

Although I was able to figure out the drawing, I need help making the wiring schematic showing all the needed chips and connections. I have been trying to figure this out for quite some time and would greatly appreciate it if you could draw the chips out on paper connecting, them with lines. Thank you so much for your time and help with this! It will help me learn a lot. :)
